Abstract:
According to one aspect, an apparatus for reducing the speed or acceleration of motion of a skateboard and its user is disclosed. According to one embodiment, the apparatus includes one or more friction elements that are removably affixed to a substantially flat resilient member at a location near the first end of the resilient member typically proximate to the rear wheel mounting truck; the resilient member is then affixed by fasteners upon its opposite and second end to the underneath face of the platform of the skateboard, typically proximate to or forward of the center of the platform. The apparatus also includes a substantially rigid linkage that penetrates the skateboard platform and is affixed to near the first end of the resilient member for the purpose of interfacing the first end of the resilient member selectively to one foot of a user of the skateboard, such that when the user desires to reduce the speed or acceleration of the skateboard the user applies to the linkage a force substantially normal to the skateboard platform and therefore the resilient member. The force applied to the resilient member causes the friction element or elements to contact the riding surface, creating by the contact of the friction element or elements with the riding surface a frictional force that is transmitted to the skateboard platform via the fixation of the second end of the resilient member to the skateboard, opposingly counteracting the velocity or acceleration of the skateboard and user, thereby slowing the motion. The frictional force is modulated by the variable force applied to the apparatus by the user.
Abstract:
The disclosure is directed to a system and method for recovery of a broadcast source. Television data is received from the source and encoded. The encoded television data is stored by either (1) appending the encoded television data to programs on a data storage or (2) overwriting an oldest program with the encoded television data if the data storage does not have capacity to append. The source is monitored for a broadcast failure. As long as the broadcast source is operational, television data is received, encoded, and stored. Once a broadcast failure is detected, selected programs on the data storage are decoded and broadcast. This decoding and broadcasting continues until the broadcast failure at the broadcast source is repaired.
Abstract:
Methods for manipulating a plurality of layered windows on a display are described. Specifically, the manipulation of layered windows includes moving a pointer to a visible portion of a partially hidden window and holding the pointer at the visible portion for a predetermined period of time. Responsive to the holding for a predetermined period of time, the partially hidden window is revealed. The manipulation of the layered windows can be used to drag and drop an icon from an active window to an inactive window. During the drag of an object, holding down a predetermined key on the keyboard can send the top-most-layered window to the back thereby disclosing other windows. If no drop occurs at the end of a drag operation, windows are returned to their original layers. However, if a drop occurs, the window in which the object is dropped becomes the topmost layer while other windows return to their original layers.
Abstract:
An apparatus for transmitting a multiplexed analog component television signal. The apparatus includes a signal source generator for generating a signal source having information regarding the number of lines per frame. A multiplexed analog component television signal generator generates a multiplexed analog component television signal having a varying number of lines per frame and including information regarding the number of lines per frame. A transmitter coupled to the multiplexed analog component television signal generator transmits the television signal to at least one remote terminal.
Abstract:
A wireless network has a plurality of nodes that are configured to communicate electrical signals via a backhaul channel in which messages hop from node-to-node through the network. The nodes have optical transmitters for communicating with tags via an optical channel that is time division multiplexed (TDM) among the nodes of the network. The nodes are configured to transmit an electrical synchronization signal via the backhaul channel and to synchronize transmissions for the optical channel based on the electrical synchronization signal. Thus, use of the backhaul channel to communicate the synchronization signal leverages the existing framework of the network in order to synchronize the optical transmitters without requiring specialized synchronization circuitry, and a robust TDM algorithm can be implemented for the optical channel with relatively low complexity and costs.
Abstract:
In one aspect, an apparatus for measuring a tension force on a net cord of a sports net is disclosed. The apparatus may include a housing configured to connect to a static post. The apparatus may also include a slidable member and attachment members. The attachment members may be configured to engage a portion of the net cord. A resilient member inside the housing may be connected to the slidable member, and an indicator member may be connected to the slidable member within the housing. The slidable member may be configured to move within the housing in response to and by a distance proportional to an amount of tension force on the net cord. The indicator member may be connected to the slidable member such that a portion of the indicator member may be exposed through a slotted opening defined in the housing.
Abstract:
Serial processing of video signals is efficiently carried out by the method and system which makes use of specifically configured bitstream processors. The particular bitstream processors utilized include specifically configured decoder blocks and encoder blocks which are uniquely designed to carry out the serial processing tasks necessary for video encoding and decoding operations. These encoder and decoder blocks are uniquely programmed within the bitstream processor, thus providing specific capabilities most beneficial when dealing with video data.
Abstract:
One embodiment includes a system for application-layer monitoring of communication between one or more database clients and one or more database servers. The system includes one or more decoders residing at a decoding layer above a network layer. The decoders reside at a first network location between one or more database clients residing at one or more second network locations and one or more database servers residing at one or more third network locations. The decoders receive database messages communicated from the database clients and intended for the database servers and database messages communicated from the database servers and intended for the database clients, decode the database messages, and extract query-language statements from the database messages. The system also includes a monitoring application residing at an application layer above the decoding layer. The monitoring application resides at the first network location. The monitoring application receives query-language statements extracted at the decoders and records observations on the database messages based on the query-language statements extracted at the decoders.
Abstract:
A wireless mesh network has a plurality of nodes. One of the nodes, referred to as a “topology building node,” is configured to discover a topology of the network. In this regard, a multicast topology message is transmitted via at least one node of the network. Each node that receive such message transmits a topology multicast reply to the topology building node which adds the transmitting node to the topology if the transmitting node is not already identified by the topology. Upon adding a node to the topology, the topology building node transmits a topology multicast command to the added node thereby causing such node to transmit a multicast topology message. Accordingly, the topology eventually receives a topology multicast reply from each node of the network allowing such node to build a complete topology of the network.
