Some embodiments include a handheld detector, comprising: detector circuitry configured to convert incident radiation into electrical signals; a processor coupled to the detector circuits; and an accelerometer coupled to the processor; wherein the processor is configured to activate from a low power state in response to a first acceleration event detected by the accelerometer.

Free-fall and impact detection system for electronic devices

An X-ray imaging device includes a color sensor configured to generate a color signal indicating a particular color sensed, an imaging matrix of pixel detector elements that are each configured to detect photon energy and generate an image signal, and a controller that is coupled to the color sensor, the imaging matrix, and the wireless transceiver. The controller is configured to receive a color signal from the color sensor, determine an identifier of the computing device external to the X-ray imaging device based on the color signal, and change at least one operational setting of the X-ray imaging device based on the identifier.

Configuring a portable x-ray detector for use with an image acquisition workstation based on color detection

An X-ray imaging device includes a first wireless communication module coupled to a first set of antennas; a second wireless communication module coupled to a second set of antennas; and a controller that is coupled to the first wireless communication module and the second wireless communication module. The controller is configured to receive a first value for a wireless performance metric for the first wireless communication module while the X-ray imaging device, receive a second value for the wireless performance metric for the second wireless communication module while the X-ray imaging device, based on the first value and the second value, determine a first wireless communication function to be performed by the first wireless communication module, and cause the first wireless communication module to perform the first wireless communication function.

Dynamic allocation of multiple wireless interfaces in an imaging device

This invention describes a novel solution to conserve battery and to overcome cold-start artifacts by maintaining the pixel charge traps at a stable value at all times. The design of NIP photodiode and TFT combination requires very low current (in order of hundreds of &#x3bc;A) to stay biased at all times. This allows the pixel charge traps to be easily maintained at a stable value with low power consumption. Power consumption is kept at a minimum by keeping all panel electronics off and only the pixels biased. In addition, keeping the pixels biased helps to overcome the cold-start artifact in the very first image.

Low power standby mode in wireless imagers

An imager includes a flat panel configured to collect charges when the imager operates in a full-power charge integration mode. The imager switches to a low-power standby mode immediately after each image acquisition in the full-power charge integration mode. Bias current flowing through the flat panel is monitored in the standby mode. The imager switches to the full-power charge integration mode when detecting a change in the bias current indicating onset of an X-ray exposure.
