Abstract: An electromechanical lock includes a housing containing a microcontroller, a power source, a cam, and a locking lever for holding a U-shaped lock bar in a closed, locked position within the housing. The lock further includes several buttons on the housing for entering a sequence of alphanumeric characters of a combination code and a Liquid Crystal Display (LCD) for showing the alphanumeric characters, independently, when entering the code. Messages may also be displayed, including advertisements and company logos, upon completion of a correct code entry to open the lock. The microcontroller stores one or more combination codes and message data and controls actuation of the cam, upon entry of the correct combination code, to momentarily release the lever from the lock bar, allowing the lock bar to be pulled out from the housing, thereby opening the lock.

Abstract: The device includes a housing having a main body including an analysis chamber with at least one chemical reagent composition contained therein and a vessel portion for receiving and capturing a fluid specimen taken from a beverage. The device is structured to transfer the captured fluid specimen from the vessel portion to the analysis chamber wherein the chemical reagent composition, when exposed to the fluid specimen, performs a visible presumptive color assay to determine whether undesirable substances, such as fulnitrazepam, sodium gamma hydroxybutyric acid or caffeine, are contained in the beverage. One or more windows are provided on the housing for viewing the results of the visible presumptive color assay. The fluid specimen and one or more chemical reagent compositions remain contained within the analysis chamber to prevent contamination of the beverage as well as tampering with the captured fluid specimen.

Abstract: A surfboard leash assembly includes an ankle band and an elongate flexible cord having a first end releasably attachable to the ankle band and an opposite second end attachable to a surfboard. A lock mechanism on the ankle band includes a foot actuated switch operable between a locked position to maintain the first end of the cord attached to the ankle band and at least one unlocked position to release the first end of the cord so that, when under tension, the cord disconnects from the ankle band.
