Abstract: A sport boot that allows for a reduced resistance plantar extension coupled with a controlled, resistive plantar flexion motion. The preferred embodiments provide a one-piece boot made of a flexible material, such as leather. A triangular portion of the boot material, from a point just posterior to the ankle opening to a larger area anterior of the ankle on both sides of the boot, is cut out. One or more piston assemblies are attached to the boot material on both sides of the cut away portion of the boot. The piston assemblies provide resistance to compression during flexion of the boot but offer no resistance to extension during plantar extension.

Abstract: Systems, methods, software, and apparatus are described for facilitating the distribution and management of fragmented content. In one embodiment, a packager packages content into fragments and generates a manifest including policies and metadata associated with the content. A downloader obtains the manifest, and uses it to obtain the content from one or more uploaders. For example, a downloader might forward a search request to one or more trackers, which, in turn, are operable to locate one or more uploaders that can meet the request, subject to any relevant policy limitations. The uploaders forward fragments to the downloader, subject to any relevant policy. The downloader assembles the content from the fragments. The operations and interactions of the entities can be subject to policy limitations associated with the fragments, the content as a whole, or the like.

Abstract: A horizontal deflection winding centering circuit includes a Darlington transistor and a diode. The Darlington transistor and diode form a non-linear network that is coupled in series with an inductor. The series arrangement of inductor and non-linear network is coupled in parallel with a horizontal deflection winding. The base voltage of the Darlington transistor is produced by a voltage divider coupled in a current path of the inductor current.

Abstract: A dynamic focus voltage generator includes a source of a flyback input signal at a horizontal deflection frequency. A double integrator is responsive to the input signal for generating a parabolic periodic signal. An amplitude detector is responsive to the parabolic periodic signal for generating a control signal that is indicative of an amplitude of the parabolic periodic signal. A comparator is responsive to a signal at a reference level and to the control signal and coupled to the double integrator for regulating an amplitude of the parabolic periodic signal in a gain control negative feedback manner. A non-linear network is responsive to the parabolic periodic signal for producing a bathtub shaped output signal that is coupled to a focus electrode of a cathode ray tube.

Abstract: A method for establishing a communication link between a transmitter and a receiver for the purpose of relaying audio material derived from an existing source to a user desiring to remain unencumbered by the source apparatus comprises the steps of placing: the receiver unit into physical contact with the transmitter unit, powering up both transmitter and receiver units, and waiting for an indication of process completion before setting the receiver unit in place. The transmitter unit searches for a free rf communication channel, initiates transmission of user-chosen audio material over permitted broadcast bands, and programs the receiver unit with information allowing it to receive on the same channel. The receiver unit is lightweight, worn in the outer canal of the ear or on the head in the conventional manner. The entire programming and transmission process takes place automatically without further user intervention.

Abstract: A food cutting board apparatus includes a cutting board with an aperture sized to receive a colored indicator. The aperture is preferably located adjacent to a corner of the board. The indicator preferably comprises a ring with a hollow cavity to enable the apparatus to be hung when not in use. A cutting board system comprises the cutting board and a plurality of differently colored indicators, each with a substantially similar structure corresponding to the shape of the board aperture. A multi-board assembly includes multiple cutting board apparatuses held by a receptacle tray. Each cutting board apparatus includes notches along the edges to provide openings for discarded food items and liquids to be disposed in a space defined by the tray. The tray includes a divider which separates the board apparatuses and divides the space therein into separate compartments.

Abstract: A communication system, extends office telephony and network data services to remote clients through the Internet, comprises a telephony server, a local area network, a server system, and a user communication device. The telephony server (e.g. a Private Branch Exchange) provides telephony services for a plurality of office lines. The local area network couples to the Internet. The telephony server and local area network may reside within an office environment. The server system couples to the telephony server and to the local area network. The user communication device establishes a first connection to the server system through the Internet. In response to the first connection, the server system automatically provides access for the user communication device to the telephony server. Also, the server system automatically invokes a call forwarding operation in response to the first connection, so that subsequent telephone calls, intended to reach the user's office line, are forwarded to the server system.

Knuckle arm 16 includes an end portion 40 which is attached to a ball stud 44. Ball stud 44 is mated with socket 26 and cooperatively forms ball joint 18. End portion 40 includes a generally circular bottom surface 52 disposed in a substantially parallel relationship to “feet” 32, 34. Two resilient elements or “pads” 62, 64 are abuttingly disposed between “feet” 32, 34 and surface 52.

Abstract: A scan frequency detector is responsive to a horizontal synchronization signal to generate a data signal that is indicative of the horizontal scan frequency. A digital-to-analog (D/A) converter produces from the data signal an analog, output signal at a first level, when the horizontal frequency is within a first range of values, at a second level, when the horizontal frequency is within a second range of values and at a third level, when the horizontal frequency is within a third range of values. A first switch of a switched S-capacitor arrangement, is turned on, when the output signal is at the first level. The first switch and a second switch of the switched S-capacitor arrangement, are turned on, when the output signal is at the second level. Both the first and second switches are turned off, when the output signal is at the third level. The third and second levels are distinguished by a level detector that includes a zener diode.

Abstract: A shock absorbing apparatus suitable for use in a motor vehicle having a first component (16) and a second component 18 movable relative to one another is described. The shock absorbing apparatus (48) includes a first, second and third metallic members (54, 74, 90) for providing positive control of the total compression of a shock absorber (14) under jounce loading. Additionally, a second hollow member (82) attaches to an elastomeric member (62), which when compressed under jounce loading retracts to provide clearance for a spring perch 28 located on a first hollow member (20).

The cutting board mounts directly within a drip pan tray and is provided with at least one notch whereby juices may flow into the tray below. The tray is provided with a pour system to provide convenient cutting, serving and pouring of the food to be served.

Abstract: A system for indicating unauthorized use of a vehicle has a display (2) which when activated by an alarm actuating device flashes alternately the word "STOLEN" and the registration number of the vehicle. The alarm actuating device comprises a housing (11) for receiving a key plug (4) and including sensing regions (12) for detecting whether resiliently mounted members (6) of the key plug (4) are in contact with their respective sensing regions (12). With an incorrect key inserted into the key plug (4) one or more of the members (6) will contact its sensing region (12) and actuate the alarm.
