Abstract: A device includes a controller. An input is coupled to the controller, the input having a set of wires to couple to a doorbell to receive an AC signal when the doorbell is actuated. An analog to digital converter is coupled to the input to convert the received AC signal to a digital signal and coupled to the controller to provide the digital signal to the controller. A transmitter is coupled to the controller to wirelessly transmit signals from the controller representative to actuation of the doorbell. An enclosure contains the controller, input, analog to digital converter and transmitter and has an opening to provide a passage outside the enclosure for the set of wires. The controller may be programmable via an optical signal and may provide alerts responsive to a temperature sensor.

Abstract: A method and apparatus for adjusting the focus of a camera. A rotatable focus member, when rotated, effects movement of an indicator element. The position of the indicator element is sensed by a sensing element and is passed to a controller within the camera. The controller prompts a motor to drive a focusing element of the camera in response to changes in the sensed position of the indicator element. The focus member effects movement of the indicator element by way of rolling resistance as opposed to sliding friction, allowing for more consistent and controlled manipulation.

Abstract: An engine for use in a thermal instrument. The engine includes an infrared camera module and may also include a visible light camera module. The engine includes several temperature sensors mounted on a printed circuit board assembly that permit the engine to provide improved radiometry functionality and improved fine offset compensation capabilities.

Abstract: A housing of a thermal imaging camera includes a camera portion, in which an thermal imaging assembly is mounted, and to which a focusing assembly is mounted, on a first side thereof, and to which a display is mounted, on a second side thereof; a handle portion of the housing extends from a bottom side of the camera portion of the housing at an angle, away from the first side of the camera portion. The housing is configured for ergonomic handling wherein an index finger of a hand may readily activate the focusing assembly, when the hand is wrapped about the handle portion of the housing. The hand may be a right hand or a left hand, and the camera may further include additional features to provide support for single-handed operation.

Abstract: A thermal imaging device includes a replaceable battery pack, which may include a shock absorbing and/or seal member. A battery portion of the battery pack includes an electrical contact and a sidewall that contains at least one battery cell, which is electrically coupled to the contact. An attachment mechanism of the battery pack is configured to engage a portion of a housing of the device, such that a portion of the battery pack forms a terminal end of the device, the battery portion is held within the portion of the housing, and the electrical contact of the battery portion is operably connected to the imaging assembly of the device. The attachment mechanism is releasable from engagement with the housing, such that an entirety of the battery pack can be completely separated from the thermal imaging device.
