Abstract: A locking system for an integrated circuit (IC) chip can include an arrangement of one or more antifuse devices in a signal path of the IC chip. The antifuse devices can be configured to operate in a first state, corresponding to a normally open switch, to inhibit normal operation of the IC chip, and to transition from the first state to a permanent second state, corresponding to a closed switch, in response to a program signal applied to at least one terminal of the IC chip to enable the normal operation of the IC chip.

Abstract: This disclosure relates generally to printed circuit board authentication, such as for protecting printed circuit boards against counterfeiting. The authentication can be implemented based on measurements from the PCB used to generate a unique signature for the PCB. The generated signature of the PCB can be evaluated to determine if the PCB is authentic or counterfeit.

Abstract: An antifuse apparatus can include a cantilever extending from a first electrode portion to terminate in a distal end. A second electrode portion can be spaced apart from the cantilever by an air gap. In response to a program voltage across the first and second electrode portions, the cantilever can be adapted to move from an unprogrammed condition, corresponding to an open circuit condition where the cantilever is spaced apart from the second electrode portion, to at least one permanent programmed condition, corresponding to a short circuit condition between the first and second electrode portions where the cantilever engages the second electrode portion.

Abstract: The present disclosure relates generally to using detected bladder events for the diagnosis of urinary incontinence or the treatment of lower urinary tract dysfunction. A system includes a sensing device comprising a pressure sensor to directly detect a pressure within a bladder. The sensing device is adapted to be located within the bladder. The system also includes a signal processing device to: receive a signal indicating the detected pressure within the bladder; detect a bladder event based the detected pressure within the signal; and characterize the bladder event as a bladder contraction event or a non-contraction event. The characterization of the bladder event can be used in the diagnosis of urinary incontinence or the treatment of lower urinary tract dysfunction.
