Abstract: A lap timing device for swimmers utilizes a proximity sensor to detect the completion of each lap a swimmer swims during a training session. The device, which is preferably portable and in the form of a starting block of standard AAU dimensions, is placed adjacent an edge of a swimming pool. The number of laps of the training session are input and the swimmer stands on the diving platform of the device. When the swimmer dives off of the platform, a switch starts a clock/counter in the device. The proximity sensor, preferably an ultrasonic transducer, detects the completion of each lap. When the predetermined number of laps is counted by the device, an alarm sounds, indicating to the swimmer the end of the training session, and the total swim time, average time per lap, fastest lap time and slowest lap time are displayed.

Abstract: A personnel suspended tent and rain guard apparatus provides a personnel compartment having an upper rectangular elongated roof and a lower generally coplanar floor with a plurality of side walls connecting said upper roof and said floor. A pair of upper load lines attached respectively to the opposite and parallel sides of the roof with each load line having its end portions adapted for suspending supporting attachment to rigid members, such as trees. A pair of lower load line floor supporting members are attached respectively to the opposite end portions of the floor and extend in directions away from the floor during operation for attachment to a desired point of rigidity. Spreader brackets are provided at each end portion of the floor for laterally stressing the window personnel compartment suspended by the upper and lower load lines above the ground as occurs during operation.
