Abstract: An organic photodetector includes: an anode; a cathode facing the anode; and an active layer disposed between the anode and the cathode and including a first layer and a second layer. The first layer is disposed between the anode and the second layer, the first layer includes a p-type organic semiconductor and an n-type organic semiconductor, and the second layer includes the p-type organic semiconductor.

Abstract: A hearing aid compatible mobile electronic device is provided. The hearing aid compatible mobile electronic device includes a wireless communication unit including a power amplification module, a power source configured to transfer a first current to the power amplification module through a sending end thereof and to receive a second current from the power amplification module through a ground terminal thereof, a line unit connected between the power amplification module and the power source and including a first line through which the first current flows and a second line through which the second current flows in an opposite direction to the first current, and a receiver configured to generate a magnetic signal for hearing aid compatibility and to receive a first magnetic field generated by the first current and a second magnetic field generated by the second current.

Abstract: A disposable biopsy device includes a vacuum generating assembly generating a vacuum. The disposable biopsy device also includes a tissue cutting assembly including a hollow outer needle having a longitudinal axis and an inner cutter needle positioned within the hollow outer needle. The tissue cutting assembly is pneumatically coupled to the vacuum assembly such that the vacuum drives a cutting motion of the inner cutter needle along the longitudinal axis of the hollow outer needle.

Abstract: The described invention provides a disposable handheld biopsy device for taking biopsies, the biopsy device comprising a tissue cutting assembly which has features to control the tissue length that will be severed by the cutting assembly; and a vacuum assembly which has features to control the vacuum level. The disposable handheld biopsy device of the described invention is simple, lightweight, portable, and cost effective to manufacture and dispose of.

Abstract: An aftermarket vehicle mount for an electronic device (e.g., a tablet computer) consists of an extensible mounting base, one end of which removably attaches to a windshield, the other end of which rotatably attaches to an electronic device holder. The electronic device holder grasps an electronic device with spring-loaded arms. The extensible mounting base has a folded configuration, in which the electronic device rests flat on the top of a dashboard, and an unfolded configuration, in which the electronic device drapes over the front of the dashboard, at an appropriate viewing angle for a passenger. In either configuration, the electronic device may be easily rotated between landscape and portrait orientations, but unwanted motion of the electronic device from sudden accelerations (e.g., from encountering a pothole) is minimized. Embodiments suitable for home and office are also contemplated.
