Abstract: Described herein are fields of exercise or therapy systems in particular exercise or therapy systems that controllably generate and maintain an unweighted environment using a mechanical system or a differential air pressure (DAP) envelope about a user so as to at least partially or completely unweight the user. This application also relates to improved control systems for pressure chambers for use in differential air pressure (DAP) systems including data collection and utilization for general fitness use, athletic use, or medical use treadmills and related software, control and analytics systems, especially as related to obtaining gait data from load cells provided in the system.

Abstract: A software distribution service provides time-based licensing of software. Third-party software is augmented with functionality to enable tracking based on usage, and is downloaded through a network to a user's workstation. A user logs into an account over the network to verify account details and a sufficient balance with an authentication server. If verified, the augmented software is activated, and the time of usage is tracked. During use, the augmented software periodically communicates with the authentication server to deduct a metered-usage fee from the user's pre-paid account balance.

Abstract: A non-invasive metering system enables on-demand, metered usage licensing of software applications. A packaging module generates a secure application package for an original, unmodified application authored by a software publisher. The software publisher need not directly modify the code of the original application. Rather, the packaging module includes, within the secure application package but separate from the code of the application itself, a shell application that controls runtime aspects of the application, such as metering of the application. The secure application package is made available to users wishing to use the application on a metered basis.

Abstract: A jostle-responsive object finder system including a user carryable and activatable code-signal wireless transmitter, and an activatible signal receiver within an object unit which is attachable to an object of the user's choice, and responsive to such a code signal, but only after the occurrence of a jostle action which is delivered to the object unit, to initiate an attention-getting response detectable by the user.

Abstract: An external signal processor is provided for use with a personal computer. The signal processor incorporates hardware components for receiving external analog or frequency signals and for converting the signals to digital form for retrieval by the computer in nibble mode. Interconnection with the personal computer is through the parallel printer port, with the signal processor installed between the computer and an external printer. Normal printer functions are available when a transparent mode is enabled. The signal processor can also monitor one or more external digital signals and output one or more digital control signals. An example of programmable control software is also provided.

Abstract: An exercise/therapy support system useable with a personal-exercise-type machine. A sonar ranging device monitors motion in the machine during exercise to produce an exercise-related, visual display which is compared, in real-time, with a preprogrammed, selected-exercise-regime display. Post-exercise data can be made available for analysis.
