Abstract: An embodiment of the invention provides a surgical tool including a handle having a channel, a tracheal hook connected to the handle, and a scalpel positioned in the channel of the handle. The tracheal hook and/or the scalpel are removably attached to the handle. The channel includes at least one first fastener (e.g., a recess); and, the scalpel includes at least one complementary second fastener (e.g., a protrusion) for engaging the first fastener. The scalpel and/or handle include a light source. The tracheal hook and/or the handle are formed from translucent material. In addition, a wire is provided having a first end connected to the handle and a second end connected to the tracheal hook. The surgical tool further includes at least one cap having a first open end, a second open end, and at least one lateral fenestration.

Abstract: A SCSI ID of a SCSI initiator device that has won an arbitration is identified on a SCSI bus and stored in a register at a SCSI device. Subsequently, a SCSI ID of a selected SCSI target device which was selected by the SCSI initiator device is identified on the SCSI bus and compared with the SCSI ID in the register. If the SCSI ID of the selected SCSI target device and the SCSI ID stored in the register are different, a SCSI command from the SCSI initiator device is processed by the selected SCSI target device. If the SCSI ID of the selected SCSI target device and the SCSI ID stored in the register are the same, the selected SCSI target device refrains from processing the SCSI command from the SCSI initiator device.

Abstract: A technique for extending the operating range of a flyforward converter to low input voltages. In one aspect, power converter includes a positive input supply rail and a negative input supply rail. A power converter input voltage is to be applied between the positive and negative input supply rails. A flyback energy transfer element having a flyback input winding and a forward energy transfer element having a forward input winding are also included. The flyback and forward input windings are coupled between the positive and negative input supply rails. Voltage control circuitry coupled to the forward energy transfer element is also included to reduce a voltage across the forward input winding, substantially to zero, when the power converter input voltage falls below a first threshold value.

Abstract: A peripheral device (which is preferably a disk drive) can automatically collect trace data upon detecting certain error conditions. The peripheral device has the ability to selectively alter the range of state data collected in a trace depending on the error type. Preferably, the device includes a programmable processor executing a control program. A set of trace switches, each enabling a corresponding set of trace points, can be independently set by the control program. An error trace identification table identifies, for each error type, a corresponding set of trace switches. If an error is encountered, the trace switches corresponding to the error type are determined from the table, and the switches are set accordingly. In another invention aspect, a set of trap switches in the device can be set to trap on the occurrence of a specific error type, thereby supporting a more detailed error analysis.

Abstract: A digital subscriber line (DSL) modem for a service area interface, which controls the power of its downstream transmissions to minimize far-end crosstalk (FEXT), is disclosed. The disclosed modem has an interface to a low-attenuation upstream facility, such as fiber optic, and includes a digital transceiver and an analog front end that is coupled to a twisted-pair wire facility in a binder. The modem also includes a memory location for storing the feeder distance between a DSL central office and the service area interface, the service area interface also coupled to a subscriber of the CO-fed communications via twisted-pair wire. Power cutback levels are applied to the downstream transmissions from the modem according to the feeder distance, so that the FEXT on the CO-fed signal is minimized without undue data rate degradation.
