摘要:
An electronic device that receives a signal indicative of the sound made my a musical instrument in order to determine the instantaneous rate of play of melodic notes on that instrument in terms of notes played per second and display the rate in real time via a display. The regularity of the musician's rate of play is further indicated by the stability of the display reading. Individual sustained melodic notes are identified utilizing differential capacitance and circuit delay time constants to generate a voltage differential in response to a step signal. The device is also selectively operable as a conventional metronome to provide an exemplary sound cue to the musician corresponding to a given number of notes per second and convertible by a switch or foot pedal to monitor the musicians rate of play as he tries to match the demonstrated rate.

An in-line coaxial circuit assembly having a first portion with a first electrical connector interface on a first end and a second portion having a second electrical connector interface on a second end. The first portion and the second portion adapted to couple together along an outer wall of at least one of the first portion and the second portion. A cylindrical outer conductor section coaxial with the outer wall may be formed in at least one of the portions. The coupling of the first portion and the second portion forms an enclosed cylindrical PCB chamber between the outer conductor section and inner conductor or outer wall, if present. A PCB may be positioned within the PCB chamber, the PCB coupled to the inner conductor through a slot in the outer conductor section, if present.

An improved shoe outsole having an elastic shank (12) and suitable for outdoor wear, outsole portions (14,16) comprised of semi-rigid material for forming same, and a shoe (10) incorporating the improved outsole are disclosed. The front outsole portion (14) has a ledge (22) extending widthwise across the back end thereof and the rear outsole portion (16) has a ledge (24) extending widthwise across the front end thereof, such that the elastic shank (12) is joinable to the outsole portions (14,16) by means extending through the shank (12) and the ledges (22,24).
摘要:
A technique for managing the streaming of digital video content to multiple clients involves identifying an attribute of a content element that is streamed to a client and selecting a protection mechanism for the content element as a function of the attribute, wherein the protection mechanism enables streaming of the content element to the clients in the event of a resource failure. In an example, the identified attribute is an indication of the popularity of the content element (e.g., as measured by the number of active streams), such that the protection mechanism is selected as a function of the popularity of the content element. In an embodiment, protection mechanisms that offer a higher level of protection are selected for the more popular content elements and protection mechanisms that offer a lower level of protection are selected for the less popular content elements.

An in-line surge suppressor having a body with a bore. The body formed from a first portion and a second portion dimensioned to couple together. An inner conductor positioned within the bore and a shorting element extending between the inner conductor and the body. The shorting element having at least two loop segments, each of the loop segments arranged in a separate plane. Each of the loop segments interconnected with at least one other loop segment by a transition section.

A method for controlling communications between endnodes in a packet-switched computer network includes dynamic window sizing and dynamic packet metering. Dynamic window sizing regularly probes the network to determine whether higher throughput is available at an increased window size, and avoids unnecessary decreases in window size after a packet is dropped or all available data has been transmitted. Dynamic packet metering regularly adjusts the rate at which packets are transmitted in response to changes in the measured propagation rate of packets through the network. To avoid unnecessary ack packets, acks are bundled together and piggybacked on returning data packets when appropriate. The invention provides control even if the address of an endnode changes. The invention also supports multiplexing several logical connections over a single transport session and combining data from several connections in a single packet, as well as construction of packets in a network-layer-independent format.
