A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.

To reduce the impact of image frequencies generated by mixing an incident carrier signal down to a relatively low intermediate frequency signal used in subsequent signal processing, a mixing frequency is selected such that the generated intermediate frequency signal has a frequency offset relative to DC that is substantially that of a single channel spacing between frequency adjacent incident carrier signals, as shown in FIG. 2. Image rejection is further improved through the integration of a current-driven polyphase filter (36) directly between an input stage (Q1 to Q4) and a mixer stage (Q5 to Q12) of an image reject mixer (FIG. 4) such as to mitigate quadrature divergence between separate in-phase and quadrature paths within the image reject mixer.

The loss of data and/or the corruption of data that may occur in flash memory when a reset signal is received during a memory write cycle is prevented by delaying reset signals sent to the flash memory for a time period sufficient for a write cycle to be completed. The loss of data and/or the corruption of data that may occur in flash memory when the power supply is interrupted during a write cycle is prevented by providing a DC-to-DC converter with one or more large capacitors in parallel with its input as the power supply to the flash memory. If the system power supply fails or is interrupted, the discharge of the capacitor(s) delays the voltage decay at the input of the DC-to-DC converter such that the output of the DC-to-DC converter remains within tolerance for a time sufficient for the flash memory to complete a write cycle.

The system includes an AC/DC voltage converter coupled to the AC voltage source for converting an AC voltage from the AC voltage source to a high DC voltage output at a first location. The AC/DC voltage converter comprises a plurality of AC/DC voltage converter components which, on the input side thereof, are connected in parallel with the AC voltage source and which, on the output side thereof, are connected serially to an electric conductor. The electric conductor extends to a plurality of voltage converters at a remote location having inputs connected serially to the electrical conductor and having outputs providing an appropriate voltage to the electrical device, the plurality of voltage converters converting the high DC voltage to either a lower DC voltage or an alternating voyage without a cooling mechanism that would otherwise be needed when less than the plurality of voltage converters are implemented to convert the high DC voltage to the lower DC voltage or alternating voltage.

Arrangement for obtaining information about objects in an environment around a vehicle, e.g., in blind spots of the driver of the vehicle, including one or more light emitting components arranged on the vehicle for emitting infrared light into the environment around the vehicle and receivers arranged on the vehicle for receiving infrared light from the environment around the vehicle. The information about the objects is obtained based on analysis of the received infrared light by a processor, e.g., the distance between the vehicle and the object, the velocity of the object and the identity of the object. Pattern recognition techniques are preferably used to obtain the desired information. Control of the vehicle can be effected based on the detection of particular objects and their position and velocity, e.g., an audio or visual warning device or a steering wheel control device.

A polyaxial ball and socket joint that can be locked into a fixed position. The fastening system consists of the polyaxial ball and socket joint used in conjunction with a bone screw having threads on one end for use in anchoring to the spine and a spherical connector on the other end operating as a pivot point about which a connecting assembly moves in a polyaxial fashion. A substantially U-shaped connecting assembly has a lower receptacle that operates as a socket for housing an upper retainer ring and a lower split retaining ring. The socket is receptive to the spherical connector which is inserted through the lower split retainer ring causing a momentary displacement thereof which allows for the positioning of the spherical connector between the upper and lower retainer rings.

A pixel image enhancement system which operates on color or monochrome source images to produce output cells the same size as the source pixels but not spatially coincident or one-to-one correspondent with them. By operating upon a set of input pixels surrounding each output cell with a set of logic operations implementing unique Boolean equations, the system generates "case numbers" characterizing inferred-edge pieces within each output cell. A rendering subsystem, responsive to the case numbers and source-pixel colors, then produces signals for driving an output device (printer or display) to display the output cells, including the inferred-edge pieces, to the best of the output device's ability and at its resolution.

The communication method entails electromagnetically delivering power from at least one telemetry antenna within the reader unit to at least one telemetry antenna within the sensing device, and controlling the power supplied to the sensing device within a predetermined operating power level range of the sensing device.

Transparent redundancy may be achieved at a MPLS-MPLS hierarchical boundary or a BMA-MPLS hierarchical boundary by utilizing local repair mechanisms extant in each domain to select automatically the same boundary network devices as the primary and secondary boundary network devices. In the MPLS domain, two LERs advertise the ability to forward traffic to a phantom LER and map all traffic originated into that domain as having been on a path originating at the phantom LER. This will cause the LERs to appear as being one hop away from the phantom LER, causing MPLS to assume the real LERs are part of a LSP terminating at the phantom LER. MPLS local repair will thus establish one of the LERs as the primary LER and the other LER as the secondary LER. In an Ethernet domain, each boundary network device is treated analogously to a router in the VRRP scheme for routers.

A two-way data communication device such as a data ready cellular telephone, a two-way pager, or a telephone communicates via a two-way data communication network with a server computer on a computer network that has an interface to the two-way data communication network, i.e, is coupled to the two-way data communication network. For example, the computer network can be a corporate wide area network, a corporate local area network, the Internet, or any combination of computer networks. The two-way data communication device utilizes a client module to transmit message including a resource selector chosen by the user to a server on a server computer on the computer network. The server processes the message and transmits a response over the two-way data communication network to the client module. The client module interprets the response and presents the response to the user via a structured user interface. Alternatively, the user transmits a request that directs the server to transmit the response to the request to another location or to another user.
