A system for providing video-on-demand service, broadband internet access and other broadband services over T-carrier systems including a pull multiplexer cherrypicker at the head end is disclosed. The pull multiplexer receives upstream requests and cull out MPEG or other compressed video packets, IP packets and other data packet types to satisfy the requests or to send pushed programming downstream. The downstream can be DSL or HFC. Each customer has a cable modem, DSL modem or a gateway which interfaces multiple signal sources to a LAN to which settop decoders, digital phones, personal computers, digital FAX machines, video cameras, digital VCRs etc. can be attached. Each gateway can coupled the LAN to a DSL line or HFC through a cable modem or a satellite dish through a satellite transceiver. A PSTN and conventional TV antenna interface is also provided.

A dual-band antenna is provided that combines two normally disparate communications modes into a single compact aperture minimizing overall mass and volume, while maintaining high performance efficiency and reciprocity of each individual mode. The antenna is compatible with both optical (near-IR / visible) and RF (microwave / millimeter-wave) transceiver subsystems for high bandwidth communications, applicable primarily to long- to extremely long-range (space-to-ground) link distances. The optical link provides high bandwidth while the RF provides a lower data-rate weather backup, accommodation for traditional navigation techniques, and assistance in cueing the extremely tight optical beam by matching the RF beamwidth to an optical fine-steering mechanism field-of-regard. The configuration is built around a near-diffraction-limited high performance primary mirror shared by both a direct-fed RF antenna design and a Cassegrain optical telescope. Material properties are exploited to combine the optical secondary mirror with the RF feed structure, providing a collimated optical beam interface at the antenna vertex.

An electronic health care management system is provided which collects both subjective and objective information regarding a patient into a clinical patient record, and uses the record to determine evidence-based recommendations. A healthcare provider may decide to implement certain recommendations, and / or provide additional interventions which are collectively implemented using automated support tools. Often, a plan can include follow-up activities which may be automatically scheduled by the electronic health care management system, and may include external scheduling programs and corresponding application-programming interfaces (APIs).

An electronic memory module according to the invention provides non-volatile memory that can be used in place of a DRAM module without battery backup. An embodiment of the invention includes an embedded microprocessor with microcode that translates the FB-DIMM address and control signals from the system into appropriate address and control signals for NAND flash memory. Wear-leveling, bad block management, garbage collection are preferably implemented by microcode executed by the microprocessor. The microprocessor, additional logic, and embedded memory provides the functions of a flash memory controller. The microprocessor memory preferably contains address mapping tables, free page queue, and garbage collection information.

An improved crimping mechanism well-suited for use with stented prosthetic heart valves. The crimping mechanism includes a plurality of jaws configured for linear non-rotational movement toward a central axis. A rotational plate is formed with a plurality of spiral grooves or tracks for engaging the jaws. Rotational movement of the spiral tracks produces linear movement of the jaws. Nesting of the inner ends of the jaws permits each to be acted on along different radial lines while their inner faces move together evenly to reduce the crimping aperture in a smooth fashion. The crimping mechanism is particularly well-suited for use with stented prosthetic heart valves, such as a prosthetic aortic valve, though it can also be applied to other stented heart valves, venous valves, and even stent grafts which tend to be fairly large.

A method for utilization within a graphical user interface having at least one pull-down menu and at least one tool bar. The method commences with a user selecting a menu heading which displays a pull-down menu in response to a first user input, such as a left pointing device button or a left mouse button. Next, a user selects a menu item within the displayed pull-down menu again utilizing the pointing device. Then the user designates a menu item for conversion by utilizing a second user input or a right mouse button. Next, the designated menu item is drug from the pull-down menu and dropped onto the toolbar in response to the pointing device and a second user input. Then the method automatically converts the dropped menu item into a selectable toolbar button within the toolbar. A user who frequently utilizes a menu item within a pull-down menu can convert frequently utilized menu items into toolbar buttons by designating and dragging the menu items and then dropping the menu item onto the toolbar utilizing a right mouse button.

A HVAC controls system for zone controls that is comprised of one or more Wall Sensor Units (WSU) and zero or more Damper / Register Units (DRUs). The invention is a low networked cost solution for residential and light commercial that is easy to install in new and existing building. The WSUs detect, log and use occupancy data to predict where in a building HVAC conditioning is needed and to save energy where it is not needed. The DRU use shape memory alloy wires to control the opening and closing of a damper plate with very little power allowing batter operation.

In a mobile telephone apparatus corresponding to dual-band provided with an RF power module to operate in two kinds of different frequencies, a common harmonics control circuit is provided to the output circuit of such RF power module to realize higher efficiency in view of controlling respective harmonics power for both band frequencies. Moreover, a means for selectively setting the bias is also provided so that the maximum efficiency can be attained depending on the output power required with respective communication systems with the bias control signal output from the CPU of the control unit interlocking with selection of frequency of the mobile telephone apparatus body.

A DC / DC converter includes an input terminal for receiving an input voltage; an output terminal for providing an output voltage; a ground terminal for providing a reference voltage; a plurality of charge pump capacitors including at least a first charge pump capacitor, a second charge pump capacitor, and a third charge pump capacitor; and a switch circuit. The switch circuit includes a plurality of switches configured to allow the plurality of charge pump capacitors connected in a hybrid parallel-series arrangement between the input terminal and the ground terminal or between the input terminal and the output terminal by selectively conducting a specified portion of the switches.

A low density parity check (LDPC) code that is particularly well adapted for hardware implementation of a belief propagation decoder circuit (38) is disclosed. The LDPC code is arranged as a parity check matrix (H) whose rows and columns represent check sums and input nodes, respectively. The parity check matrix is grouped into subsets of check sum rows, in which the column weight is a maximum of one. The decoder circuitry includes a parity check value estimate memory (52). Adders (54) generate extrinsic estimates, from immediately updated input node probability estimates, and the extrinsic estimates are applied to parity check update circuitry (56) for generating new parity check sum value estimates. These parity check sum value estimates are stored back into the memory (52), and after addition with the extrinsic estimates, are stored in a column sum memory (66) of a corresponding bit update circuit (60) as updated probability values for the input nodes.
