Wow this is a cool iPhone application!
Introducing Helios - An iPhone/iPod Touch application that graphically predicts the path of the sun from dusk to dawn, on any given day, in any given place.
Designed as an aid to Cinematographers and Stills Photographers working in natural light, Helios is essential to anyone who needs to plan a day around the constantly changing character of sunlight. Gaffers, Grips, Location Managers, Production Designers and First Assistant Directors will already be aware of the value of this information. Other professionals, from Architects and Surveyors to Electricians and Landscape Gardeners can now predict sun exposure in the field, without the need for complex tables or graphs.
Helios operates in 3 modes:
HelioMeter is a graphical representation of the sun's position on a compass dial (azimuth) for any time of day, showing the sun's elevation and proportional length of shadow an object would cast.
SkyView is an overall view of the sun's path in the sky through the day
Inclinometer View predicts the sun's height at any given time in the day. Essentially an electronic inclinometer that reads in both time and angle.
Raw Data view provides numerical information where figures are preferable.
Helios has an internal database of over 30,000 locations around the world, providing longitude, latitude, timezone and daylight savings information. There is an ability to save favorite locations and add the current location from GPS data (where a signal is available). Core functionality is not reliant on cellphone reception. Likewise Helios will work on the iPod Touch though you have to select a nearest location from the database or manually enter the GPS coordinates.
Utilizing algorithms created by the National Renewable Energy Laboratory and The National Geophysical Data Center to predict the sun's movement (including nutation offsets) and magnetic declination, Helios is accurate to a tiny fraction of a degree.

Rieker's Digital Boom Angle Indicator Remote Inclinometer Package (model RDSR3-BA-09) is an extension of the RDI series of digital inclinometers. The RDSR3 is supplied as a calibrated set featuring an environmentally sealed measurement sensor package and a separate LCD display box (connected by an interface available in various lengths). All of the standard RDI features have been incorporated into this remote sensing package, modified specifically to comply with OSHA and other safety regulatory agencies specifications for Boom Angle Indicators.
The LCD displays angle in degrees with 0.1° resolution. The display model comes standard with green, yellow, and red LEDs (fully adjustable trip setting) provide the operator a bright fast visual warning of safe and unsafe operating conditions. The green light indicates safe operating zone, yellow as the early warning zone, and red as the danger zone. An optional audible alarm model is also available - the red LED on the front panel display is tied directly to the buzzer.
The digital display model also provides relative zero and min/max functions. The relative zero allows the operator to temporarily zero the digital readout to obtain relative slope changes. The min/max function provides the smallest and largest angle the device has sensed since the last reset.
The remote box has built in mounting feet for easy field installation and zero calibration.
The level of technology offered by Pump-Off Controllers has reached a point of maturity that justifies application in most areas implementing artificial lift with beam pumps. The Cost savings offered by POCs is thoroughly proven, and economic analysis usually indicates system pay out within one to two years. In addition, equipment has been operating in a number of environments worldwide for over a decade.
Pump-off Controllers are micro-processor-based devices capable of autonomous operation, and are primarily applied in conjunction with sucker rod pumps. Controllers monitor for pump down conditions, defined as the state when fluid in a reservoir is insufficient to warrant continued pumping. When fluid falls below a certain level, pumps are shut down until those levels are restored. Allowing pumps to run only when sufficient fluid is available for lift provides clear advantages, including efficient use of Energy, minimal maintenance costs and optimum production.
The methods used by pump-off controller to attain those advantages vary, and most units use one or a combination of a number of system variables. Units can be configured to monitor:
Figure A illustrates typical techniques used to monitor these variables. Advanced POCs support provisions for telemetry to a master computer station, enabling all well parameters and control functions to be handled remotely. Furthermore, a single controller can be employed to control one or a number of wells at any one time.
One major oil company has been involved with computerized pump off control work since the late 1970's. Employing a variety of methods in the Permian Basin in West Texas through the years, fields have realized noticeable success utilizing a system based solely on load and position. Both single and multiple-well devices using a combination of radio and hard-wired cable communications have been installed. Figure B depicts a composite field application.
The constant movement of the beam has little or no effect. On the downside, temperature effects on the walking beam can be very pronounced, placing the burden of adjustment on the electronic package. Also, because the fundamental technique is indirect, it is inherently less accurate than a direct approach.
Polish Rod-mounted cells, on one hand, have to be removed during workover, require running cables somewhat obtrusively from the frame, and are under the constant grinding, sometimes pounding, action of the girdle. On the other hand, superior accuracy permits eventual processing by sophisticated computer analysis programs. Either type of cell functions suitably for simple pump-off control activity.
The position of the beam can be derived by using a proximity switch to monitor counterweights, a resistive pot mounted underneath the I beam, or an inclinometer mounted directly to the walking beam. Proximity switches are sufficient for low cost controllers, although POC systems based on proximity switches tend to assume that upstrokes and downstrokes are of equal duration. Of course, that is rarely the case.
Resistive pots have limited lifetimes, frequently rated at 1,000,000 rotations. For a rod pump running at six strokes a minute, resistive pot failure can occur in as little as four months. Inclinometers, while costing slightly more, have a virtually unlimited lifetime, which generally justifies the added expense.
Rieker Incorporated Introduces the New Dual Axis MEMs based inclinometer to the H4 Series
The H4PD sensor provides dual axis inclination sensing in a rugged environmentally protected housing. This unit incorporates a MEMS (Micro-Electro-Mechanical Systems) sensing element referenced to gravity with integrated temperature compensation over the industrial operating range of –40º to +85ºC. The PWM (Pulse Width Modulated) output is linear with respect to the input angle directly.
Small dimensions and common footprint make it easy for field replacement.
The housing footprint is designed for retrofitting in the field without re-drilling mounting holes (common placement of center and slider flanges).
Abstract: Derivation of p-y curves from lateral load tests on deep foundations is a tedious and expensive task, requiring large numbers of strain gages along the length of the pile to develop bending moment versus depth relationships. A method is proposed which allows derivation of p-y curves from simple inclinometer data using a least-squares regression technique. Inclinometer measurements can and have been routinely made on lateral load tests of piles and drilled shafts. The method outlined in this paper provides a means of “calibrating” p-y curves using data from tests where only inclinometer data are available and promises to allow a substantial improvement in the database of load tests from which the empirical p-y curves used in design are based.

An inclinometer or clinometer is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator. Clinometers measure both inclines (positive slopes, as seen by an observer looking upwards) and declines (negative slopes, as seen by an observer looking downward).
Early inclinometers include examples such as Well's inclinometer, the essential parts of which are a flat side, or base, on which it stands, and a hollow disk just half filled with some heavy liquid. The glass face of the disk is surrounded by a graduated scale that marks the angle at which the surface of the liquid stands, with reference to the flat base. The line 0.——0. being parallel to the base, when the liquid stands on that line, the flat side is horizontal; the line 90.——90. being perpendicular to the base, when the liquid stands on that line, the flat side is perpendicular or plumb. Intervening angles are marked, and, by the aid of simple conversion tables, the instrument indicates the rate of fall per set distance of horizontal measurement, and set distance of the sloping line.
The earliest electronic inclinometers used a weight, an extension, and a potentiometer. Early in the 1900's (circa 1917) precision curved glass tubes filled with a damping liquid and steel ball were introduced to provide accurate visual angle indication. Common sensor technologies for electronic tilt sensors and inclinometers are accelerometer, liquid capacitive, electrolytic, gas bubble in liquid, and pendulum. MEMS (Micro-Electro-Mechanical Systems) technology is becoming the new standard due to their tiny size and low cost.
Often in a rollover accident, the driver and passengers are unable to call for help, the researchers said. So, unless the accident occurs on a busy road, rescue is unlikely to arrive quickly.
Now Debopam Acharya and colleagues at Georgia Southern University are developing a system that will determine the nature of an accident and automatically call emergency medical services for possible action.
Prompt communication is crucial during life-threatening events, such as fire, floods, explosions and traffic accidents, and is especially true for vehicle rollovers and crashes, Acharya said, noting such situations can be even more dangerous for military personnel during training or maneuvers off-road and in remote locations.
The system called SAVE uses inexpensive sensor technology, including an inclinometer to detect rollover, and powerful wireless technology to assess vehicle conditions. The researchers said it can monitor vehicle incline, temperature, deceleration and airbag deployment. SAVE is also coupled to a global positioning system device so emergency services can locate the accident quickly.

I don't really know the inner workings of renowned crapgadget manufacturer Brando. I assume, much like Family Guy episodes, their products are composed by a tank full of playful manatees, dunking balls featuring random gadget features through hoops according to their strange under-seacow whims. Most of the time what they come up with is crap, but every so often, they come up with a good one.
And this is that good one: a three-axis bubble mount that fits into the flash bulb socket of your camera. Sure, for most shots outside of wedding and school pictures, mathematically perfect levelness isn't terribly important if you've got the other fundamentals right. But for $11, this could go into your camera bag without a single wince of regret, just in case.
