Abstract: A material-actuated door includes a door housing including a flexible material; and one or more least one Shape Memory Alloy (SMA) actuators embedded in the door housing. Each SMA actuator is elastically biased in a first actuator physical state and is configured to transition into a second actuator physical state in response to receiving electrical current. The material-actuated door is transitioned into a first door position in response to disconnecting the electrical current to the at least one SMA actuator, and is transitioned into a second door position in response to delivering the electrical current to the at least one SMA actuator.

Abstract: The present disclosure provides a firearm monitoring and notification apparatus to allow users to monitor a firearm without interfering with the accessibility to the firearm. The firearm monitoring and notification apparatus mitigates common risks surrounding unauthorized access and tampering through deterrence and notification strategies.

Abstract: A defective pixel detection and correction mechanism for use in an image sensor integrated circuit determines whether a current pixel is a defective pixel in a consistent manner from frame to frame. The defective pixel detection and correction mechanism also replaces defective pixels with stable replacement values. The defective pixel detection and correction mechanism has a defective pixel detection mechanism that employs a look-up table with defective pixel locations for providing a non-varying determination of whether a pixel is defective or non-defective. The defective pixel detection and correction mechanism also has a defective pixel correction mechanism that employs a consistent replacement choice facility to provide a previous pixel value in the same frame, on the same row, and a predetermined number of pixels from the current pixel location as a replacement value and a replacement unit (e.g., multiplexer) for replacing the defective pixel value with the replacement value.
