Abstract: Wireless occupancy sensors and methods for using the same are provided. In some embodiments, a occupancy sensor comprises: a housing that includes a window positioned at a top portion of the housing; a battery at a lower portion of the housing; a first magnetometer that detects changes in a magnetic field when a vehicle moves over the first magnetometer; an optical sensor that detects one or more objects in a field of view of the optical sensor through the window; a transmitter for transmitting sensor data to a gateway device, and a processor that controls the first magnetometer, the optical sensor, and the transmitter.

Abstract: Systems and techniques are provided for biometric case design. According to an embodiment of the disclosed subject matter, a biometric input may be received at a biometric input device of a computing device. The biometric input may be generated through user interaction with the biometric input device. Biometric data may be generated from the biometric input. A biometric design may be generated based on the biometric data. The biometric design may be printed on an accessory for an electronic device with a printer co-located with the computing device.

Abstract: Described herein are systems and apparatuses for detecting and sharing characteristics of a ride on a watercraft. In general, a watercraft apparatus may include at least one fin coupleable to a bottom portion of a planar body. In a preferred embodiment, the fin may define a fully enclosed cavity configured to receive a ride tracking device. In general, a watercraft system may optionally include a planar body configured for moving across a water surface and for carrying a rider. In general, a watercraft apparatus may include at least one fin coupled or coupleable to a bottom portion of the planar body. In a preferred embodiment, the fin may define a fully enclosed cavity, and a ride tracking device may be disposed within the cavity.
