Moreover, the journalist can easily become part of a human intelligence network, and draw upon the intellectual resources and technical photographic skills of a large community. Because of the journalist's ability to constantly see the world through the apparatus of the invention, which may also function as an image enhancement device, the apparatus behaves as a true extension of the journalist's mind and body, giving rise to a new genre of documentary video. In this way, it functions as a seamless communications medium that uses a reality-based user-interface.

The driving and control device according to the present invention provides a desired switched current to a load including a string of one or more electronic devices, and comprises one or more voltage conversion means, one or more dimming control means, one or more feedback means and one or more sensing means. The voltage conversion means may be a DC-to-DC converter for example and based on an input control signal converts the magnitude of the voltage from the power supply to another magnitude that is desired at the high side of the load. The dimming control means may comprise a switch such as a FET, BJT, relay, or any other type of switching device, for example, and provides control for activation and deactivation of the load. The feedback means is coupled to the voltage conversion means and a current sensing means and provides a feedback signal to the voltage conversion means that is indicative of the voltage drop across the current sensing means which thus represents the current flowing through the load. The current sensing means may comprise a fixed resistor, variable resistor, inductor, or some other element which has a predictable voltage-current relationship and thus will provide a measurement of the current flowing through the load based on a collected voltage signal. Based on the feedback signal received, the voltage conversion means can subsequently adjust its output voltage such that a constant switched current is provided to the load.

An acoustic control system for an electronic musical instrument, which can obtain optimal acoustic characteristics irrespective of whether or not a low range speaker is attached to a body thereof. A piano body has high range and mid range speakers. A low range speaker is removable from the body. A stand-excluding switch designates a first speaker-use mode for using the high range and mid range speakers alone, and a stand-including switch designates a both speaker-use mode for using both the high range and mid range speakers and the low range speaker. A ROM stores stand-excluding and stand-including factors for setting acoustic characteristics in the two modes, respectively. A CPU reads one of the factors, which corresponds to the mode designated by the stand-excluding or stand-including switch. A tone generator circuit generates a musical tone signal to be reproduced in one of the modes, based on the read factor.

In one exemplary embodiment, the device includes a ferrite core comprising multiple inductors and optimized for electrical and magnetic performance. Improvements in performance are obtained by, inter alia, control of the properties of the gap region(s) as well as placement of the windings relative to the gap. The magnetic path properties of the inductors at the ends of the device are also optionally controllable so as to provide precise matching of inductances. Optionally, the device is also self-leaded, thereby simplifying its installation and mating to a parent device (e.g., PCB). Methods for manufacturing and utilizing the device are also disclosed.

A system for adding funds to a handheld gaming machine. The system includes a portable digital wallet that wirelessly communicates with a handheld gaming machine (“handheld”). The digital wallet stores an amount of funds or funds associated with a remotely stored player account, and is used by the player to add credits to a handheld. The credit meter may be stored remotely, though the player perceives that the funds are actually being transferred via the digital wallet. Other funding techniques include a kiosk that accepts cash or credit / debit cards and dispenses tickets or other media that encodes information representing an amount of funds. The player uses this media to add credits to the handheld. The media may be player-dependent such that the player's identity is somehow linked to the media or it may be player-agnostic such that the player's identity is not linked to the funds associated with the media.

The disclosed method, apparatus and system are capable of identifying and tracking memory usage to minimize power consumption in a way that lessens the detrimental effects of “throttling” or reduced power modes for memory devices.

A telemetric tibial tray includes a lower plate that defines a plurality of cylindrical transducer cavities having circular load diaphragms. An upper plate is attached to the lower plate through support posts projecting from the load diaphragms. The support posts have a circular cross-section and a diameter of about 5.0 mm. The lower plate further defines wiring channels communicating between the transducer cavities and a central cavity housing the circuit board for the telemetric tray. The wiring channels are arranged at a 45 degree angle relative to the sagittal plane of the knee joint in order to reduce the effects of the wiring channel intersection on the strain sensitivity of the tray. Each transducer cavity includes a radial strain gage array with four pairs of radially aligned strain gages, each pair aligned at a 45 degree angle relative to the sagittal plane of the knee joint. Each pair of strain gages includes an inner gage positioned at the point of maximum positive micro-strain across the diaphragm when loaded, and an outer gage positioned at the point of maximum negative micro-strain, to thereby increase the differential strain measured by the gages and increase the strain sensitivity of the tibial tray.
