This disclosure provides systems, methods and apparatus for a engine start system. In one aspect, the engine start system includes: a booster battery selectively connected in parallel with the primary batteries of the engine. The booster battery is disconnected when the battery voltage of the primary batteries is below a first target voltage. The booster battery is connected when the battery voltage of the primary batteries is at or above the second target voltage, or in response to an external input.

Wearable light device for providing additional light for activities in low light includes a wearable mount () including a light system () and power source (). Light system () includes one or more arrays of light sources such as light-emitting diodes (). Photo sensor () detects ambient light or emitted light returned from a reflective surface and causes control circuit () to dim light emission.

Wearable light device with optical sensor

The present invention relates to a method and apparatus for testing electrical traces wherein ultraviolet wavelengths from a laser source and visible wavelengths from a scanning camera are focused to a common focal plane. In a first embodiment of the method and apparatus, the wavelengths are commonly focused using an auxiliary lens having a power sufficient to accommodate the difference between the focusing plane of the ultraviolet laser source and the scanning camera. In a second embodiment, the wavelengths are commonly focused by moving the camera optics of the scanning camera relative to its visible light source. Both of these methods and apparatuses employ a fused silica lens system, avoiding the use of calcium fluoride.

Refocusing wavelengths to a common focal plane for electrical trace testing

A tester ( ), for testing electrical trace ( T) without electrical connection to test trace ( T), generally comprises an electro-magnetic source ( ), such as a laser ( ) for providing a beam ( ) of electro-magnetic radiation, such as of ultraviolet light, directed on a single test trace ( T) for producing a photoelectric effect on test trace ( T) liberating electrons therefrom, a collector ( ) disposed near test trace ( T) for collecting liberated electrons, and a collector circuit ( ) electrically connected to collector ( ) for supplying a positive potential thereto and including a meter ( ) for measuring the photoelectric current to collector ( ) from trace ( T).

Apparatus and method using photoelectric effect for testing electrical traces

A tester for electrical traces such as on a circuit board generally comprises an electromagnetic beam source such as a laser producing an ultraviolet beam, a vacuum chamber, an electrode circuit including electrodes and corresponding electronics including ammeters for measuring photoelectron flow between traces and electrodes, a controller, laser beam optics, an image acquisition system, and a pair of broadband UV lights. The board containing traces under test is disposed in the vacuum chamber at lowered pressure with grid electrodes lying close to the trace area on each side of the board. Electrode electronics selectively maintain a known potential on each electrode. The exact location of traces are determined by an image acquisition system. The board and traces are initialized to a known voltage. Photoelectric effect using ultraviolet laser beams is used to determine continuity between two points on a trace and shorts between traces.
