TL;DR: In this article, a bookmarking system is provided that includes a user input device and a network server, where a person who is viewing a program, e.g., watching a network news program on television, can bookmark an archived version of that program for future reference.
Abstract: A bookmarking system is provided that includes a user input device and a network server. A person who is viewing a program, e.g., watching a network news program on television, can bookmark an archived version of that program for future reference. The viewer utilizes the user input device to communicate to the network server the identity of the program of interest. The network server uses the identification information for the program of interest to identify a URL for the archived version of the program. The network server transmits the URL for the archived program to the personal computer of the viewer.

TL;DR: In this paper, a keyboard for use with a standard personal computer includes an alphanumeric key array having a plurality of alphumeric keys arranged in a generally orthogonal, concave array.
Abstract: A keyboard for use with a standard personal computer includes an alphanumeric key array having a plurality of alphanumeric keys arranged in a generally orthogonal, concave array. A home row of keys defines a reference position for the fingers of the operator. A liner array of function keys is provided and positioned above the reference position and tilted toward the operator. A generally orthogonal array of auxiliary keys is also positioned above the reference position. The array of auxiliary keys is rotated with respect to the reference position to accommodate the natural angle of the thumb of the operator to the index finger. A palm rest is provided for receiving the palm of the operator while the operator is manipulating the plurality of alphanumeric keys. The palm rest is positioned above the reference position defined by the home row so that during operation of the alphanumeric keys, the fingers of the operator extend downward from the palm rest in a natural curved manner.

TL;DR: In this article, a method and apparatus for recording and playback of transport stream packets including multiplexed audio, video and other data streams is presented, including a spooler card and a storage controller card incorporated into an otherwise conventional personal computer.
Abstract: A method and apparatus for recording and playback of transport stream packets including multiplexed audio, video and other data streams. The transport streams may be generated in accordance with an MPEG-2 standard. In a record mode, an arrival timestamp is generated for each input transport packet to be recorded in a peripheral storage device. A given arrival timestamp indicates the arrival time of the corresponding transport packet in the recording system. Each of the transport packets are then stored with their corresponding arrival timestamps. The record mode may utilize a packet identifier (PID) decoder to perform packet filtering such that only incoming transport packets with selected PIDs are stored. In a playback mode, transport packets and corresponding arrival timestamps are retrieved from the storage device and the arrival timestamps are utilized to direct synchronous delivery of the transport packets to, for example, a decoder or a transport stream broadcast system. The playback mode may detect a timestamp discontinuity code in one or more of the arrival timestamps, and adjust the playback system time clock accordingly. The playback mode may also provide null packet interleaving in which a selectable number of null packets are inserted between each valid transport packet to thereby provide a selectable fixed-rate transport packet output. The recording and playback features may be implemented using a spooler card and a storage controller card incorporated into an otherwise conventional personal computer.

TL;DR: In this article, a method of passing information between two or more information handling devices is described, where a device intended to receive transmitted data evaluates the data format hierarchy and determines the format in which the data is then received thereby.
Abstract: A method of passing information between two or more information handling devices is described. Such information handling devices might be a printer 342, a personal computer 343, or a scanner 344. Means for communication of information between information handling devices in the form of a network 341 and network connection means 345 exist. The information transmitted comprises a data format hierarchy, wherein a device intended to receive transmitted data evaluates the data format hierarchy and determines the format in which the data is then received thereby. Advantageously, the receiving device determines the format in which the data is then received by a response to the transmitting device comprising a path through the data format hierarchy, and all data formats comprise one or more of a plurality of data format types, and wherein for each data format type, there exists a data format receivable by all information handling devices supporting that data format type. It is advantageous in implementation if the method of passing information further comprises requests for content data for a chosen path through the data format hierarchy and responses to such requests.

TL;DR: In this paper, the authors present an energy monitoring device that can identify an electrical device coupled to a power supply, and a state of the electrical device, from a change in successive measurements of the power supply.
Abstract: Devices and methods for identifying an electrical device, and its state, in a network of electrical devices are disclosed. An energy monitoring device is programmed to identify an electrical device coupled to a power supply, and a state of the electrical device, from a change in successive measurements of the power supply. Algorithms for determining a load signature for an electrical device and its state are disclosed. A stored table of load signatures for states is used to identify devices, and states. Energy monitoring information is collected and presented to the user on a display, a remote display, or is transmitted over a network to a remote device such as a personal computer, personal digital assistant, an iPhone, a cell phone, voice mail, email, or text message.
