An electrosurgical system comprises a generator and an instrument including a first electrode, a second electrode, and an insulating spacer separating the first and second electrodes. The generator repeatedly measures a characteristic of the radio frequency output such as the impedance between the first and second electrodes. The generator analyses the impedance measurements, and interrupts the radio frequency signal when the rate of change of the impedance is such as to indicate the onset of a “flare-out”. In this way, the power is reduced before the flare-out leads to permanent damage or failure of the instrument.

A surgical instrument having a locking mechanism for preventing an output shaft of the surgical instrument from rotating and a further locking mechanism for mounting a battery pack to a distal end of a housing of the surgical instrument. The surgical instrument further includes a clutch mechanism for limiting the torque of a drive shaft of the surgical instrument. The locking mechanism for preventing the output shaft from rotating includes a locking switch which mates with a locking cap disposed on the output shaft. The locking mechanism for mounting the battery pack to the housing includes a groove at the distal end of the housing and a retaining ring which engages the groove when the battery pack is mounted on the housing. The clutch mechanism includes a clutch plate that interfaces with both the output shaft and the drive shaft and prevents failure of the motor shaft.

A source computer 8 stores updated data that is to be distributed to a plurality of destination computers (12 to 30). The destination computers (12 to 30) are divided into groups sharing a common priority level (5, 4, 3, 2, 1). Each of these groups is then associated with a push update task to be executed by the source computer 8. These push update tasks are then sequentially executed. If a particular group of destination computers exceeds a threshold size, then it may be further divided in accordance with a hierarchy of splitting rules. The push update tasks use multicasting to transfer the update data to the destination computers within their groups in a manner that reduces network traffic.

In response to determining that a potential fault is going to occur, the disclosed system automatically alerts the vehicle driver, automatically schedule a maintenance visit, automatically check the fleet inventory for components required for a maintenance visit and order unavailable components, and automatically dispatch the components to the mechanic.

Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore.

A method for a data transmission with ARQ protocol using multicast groups such as GSM, GPRS or UMTS in a mobile communication system is described. Data is transmitted in data blocks (PDU) from a transmitter (T) to a plurality of receivers (R1-RM), said data blocks (PDU) being identifiable by an identification (e.g. a sequence number). The receivers (R1-RM) send status indications to the transmitter (T) whether a data block (PDU) is correctly received. The transmitter (T) is adapted to perform retransmissions according to the status indications and has a transmission window comprising the transmission status for the data blocks (PDU) according to their identification. In the method, a synchronization to the transmitter (T) is performed for at least one first of said receivers (Ri), wherein a range of identifications of transmitted data block (PDU) is selected in said synchronization. The transmitter (T) deletes the transmission status for the selected range of identifications from the transmitter window and the first receiver (Ri) stops sending status indications for the data blocks (PDU) corresponding to the selected range of identifications. In addition, a transmitter and a computer program implementing the method are described. As an example the transmitter can be a RNC extending the RLC and MAC-HSPDA protocols standardized by 3GPP for obtaining efficient and reliable point-to-multipoint radio links.

An exposure apparatus exposes a substrate with exposure light that passes through a liquid. The exposure apparatus comprises: a porous member that has a first surface, which is capable of opposing an object disposed at an irradiation position of the exposure light, and a second surface, which is opposite the first surface, and forms a first space that is capable of holding the liquid between the first surface and the object; a supply port, which is capable of supplying the liquid to the first space; a prescribed member, which forms a second space that faces the second surface; an adjusting apparatus, which is capable of decreasing a pressure in the second space such that the liquid in the first space moves to the second space via holes in the porous member; and a control apparatus, which controls an operation of supplying the liquid via the supply ports and a pressure adjustment operation performed by the adjusting apparatus. The control apparatus repetitively executes a first operation, which supplies the liquid to the first space, and a second operation, which stops the supply of the liquid to the first space and negatively pressurizes the second space such that the liquid is substantially eliminated from the first space, to clean the porous member.

If a target-image portion to be detected is detected anew, an evaluation value of this target-image portion is calculated. If the target-image portion is detected anew, it is determined whether the number of target-image portions has exceeded n owing to such detection. If, in a case where n has been exceeded, information concerning a target-image portion having an evaluation value smaller than that of the newly detected target-image portion has been stored, then the information having this evaluation value is deleted from a list and the information concerning the newly detected target-image portion is stored in the list. Since the number of items of information stored in the list will not exceed n, it is possible to avoid a malfunction that can occur if processing is executed following storage of a large number of items of information.

The invention is intended to reduce disk access during data transfer from a disk in which occurrence of failure is anticipated to a spare disk as much as possible so that occurrence of double-failure is prevented in advance. When occurrence of failure in a disk which configures a RAID group, contents stored in the disk is copied to the spared disk. Simultaneously, another RAID group is paired with the above described RAID group and a secondary volume is provided therein. A write request is directed to the secondary volume. A differential bitmap controls a update data. Data which is not updated is read out from the primary volume, and data which is already updated is read from the secondary volume. When data transfer is completed, contents stored in the secondary volume are copied to the primary volume.

The present invention facilitates clock and data recovery (330,716/718) for serial data streams (317,715) by providing a mechanism that can be employed to maintain a fixed tracking capability of an interpolator based CDR circuit (300,700) at multiple data rates (e.g., 800). The present invention further provides a wide data rate range CDR circuit (300,700), yet uses an interpolator design optimized for a fixed frequency. The invention employs a rate programmable divider circuit (606,656,706) that operates over a wide range of clock and data rates (e.g., 800) to provide various phase correction step sizes (e.g., 800) at a fixed VCO clock frequency. The divider (606,656,706) and a finite state machine (FSM) (612,662,712) of the exemplary CDR circuit (600,650,700) are manually programmed based on the data rate (614,667). Alternately, the data rate may be detected from a recovered serial data stream (718) during CDR operations (on-the-fly) utilizing a frequency detection circuit (725) to automatically program the divider (706) and FSM (712) to provide CDR circuit operation at the nearest base clock rate (716).
