    摘要: The invention detects the loft time and/or speed of a vehicle, such as a sporting vehicle, during activities of moving and jumping. A loft sensor detects when the vehicle leaves the ground and when the vehicle returns to the ground. A microprocessor subsystem converts the sensed information to determine a loft time. A display shows the recorded loft time to a user of the system. In addition, a speed sensor can detect the vehicle's speed for selective display to the user. The invention can be used, for example, in sporting activities such as snowboarding where users loft into the air on ski jumps and catch "air" time but have no quantitative measure of the actual time lapse in the air. Therefore, users in skiing can use invention to record, store, and playback selected information relating to their sporting day, including the total amount of "air" time for the day and information such as dead time, i.e., time not spent on the slopes.

    摘要: The invention relates to a portable distance tracking system for use by a player on a playing field. The system includes a mobile interface unit that has a memory element, position interface electronics, a data processor, and a player interface. The memory element stores digitized map representations of playing fields. The position interface electronics receivers position indicative signals that are representative of a geographical location of the mobile unit from an external source. The data processor couples to the memory element and to the position interface electronics and correlates the geographical location to a field location of the mobile interface unit on the playing field. The processor also determines the distance from the mobile interface unit to a first landmark. The player interface is coupled to the data processor and communicates the distance between the mobile interface unit and the first landmark to the player. According to a preferred embodiment, the playing field is a golf course and the first landmark is a flag location at a select hole on the golf course.
