摘要:
A tool changer including male and female flanges for connecting end effectors to robot arms. A male flange having a tapered projection is inserted into a tapered opening in a female flange having a rod coaxial with the diameter of the tapered opening. A rotatable locking stud is aligned within an opening in the male projection and includes a slot having locking grooves at its lower end. The stud is rotated through an angle causing the male and female flanges to be drawn together until the cooperating tapers are seated together. A spring retains the flanges in the locked position. A cooperating pin and pin receiving socket respectively provided on the male and female flanges at locations displaced from the male and female tapers are utilized to assure proper orientation between flanges and to prevent rotation of the flanges. Electrical terminals on the male connecting flange engage cooperating conductive terminals on the female flange, providing an electrical path between electrical sources and load utilization devices on the end effectors. Pneumatic couplings are also provided between the male and female flanges. A plurality of removable flange identifying pins are arranged along the circumferential wall of the male flange for electrical engagement with cooperating sensors provided in each tool holder of a tool crib for identifying the type of end effector being stored. A single operator arm is provided in the tool crib for simultaneously moving the operating arms of all of the tools in the tool crib respectively to the engaged and disengaged positions.

A wireless control system includes a device for sending a wireless signal, a receiver for receiving the wireless signal, and circuitry for processing the wireless signal. The circuitry includes a learn mode in which a device is associated with the control signal to the exclusion of commands from other devices not associated with the circuitry. The device transmits a wireless signal redundantly over a plurality of frequencies. The control system may chooses a signal frequency and receiver combination to maintain a quality signal.

A laminated negative pressure wound dressing system and method is described. The wound dressing is disposed in the wound in layers including at least one bioabsorbable layer that contacts the wound bed, a bioabsorbable fluid communicating layer, an atmospheric barrier layer, and a tube for applying a negative pressure to the wound bed. Ingrowth of granulation tissue into the bioabsorbable wound bed layer does not need to be inhibited as the bioabsorbable material need not be removed during dressing changes. A kit containing the components of the wound dressing system is also disclosed as well as a method for applying the dressing.

An arm is pivotally coupled to a support structure at one end and a patient care equipment support, such as a service head, is pivotally coupled to the arm at the other end. The arm has a first portion and a second portion coupled to the first portion for extension and retraction relative to the first portion. Brakes are provided to brake the extension and retraction of the portions of the arm, to brake the pivoting movement of the arm relative to the support structure, and to brake the pivoting movement of the patient care equipment support relative to the arm. Each of the brakes is releasable.

A patient support apparatus comprising a wireless control system is provided. The wireless control system includes a device for sending a wireless signal, a receiver for receiving the wireless signal, and circuitry for processing the wireless signal. The circuitry may have a learn mode in which a device is associated with the control signal to the exclusion of commands from other devices not associated with the circuitry. Also, the device may transmit a wireless signal redundantly over a plurality of frequencies. The control system may choose a signal frequency and receiver combination to maintain a quality signal. The device may be limited provide commands to operate a function of the patient support apparatus only when the function has been enabled through a sequence of input activations. The wireless control system is capable of controlling any of a number of functions associated with the patient support apparatus. Illustratively, the control system operates a patient repositioning apparatus. The repositioning apparatus includes a retractor, a tether coupled to the retractor and configured to be retracted by the retractor, and a sheet attachment device coupled to the tether opposite the retractor, the sheet attachment device configured to engage a sheet on the patient support apparatus. The sheet attachment device includes a user interface configured to provide wireless inputs to the retractor. The retractor includes a controller configured to receive inputs, process the inputs, and provide outputs to activate the retractor.

A method of managing storage comprises connecting a number of virtual disks to a disk controller loop of a disk controller, and mounting a portion of the number of virtual disks to the disk controller wherein a storage map is loaded into a fixed-size memory of the disk controller for each virtual disk mounted. The method further comprises receiving a request for data contained on an unmounted virtual disk with the unmounted virtual disk having a storage map of certain size. A sufficient number of mounted virtual disks are dismounted to allow the fixed-size memory to accommodate the certain size of the unmounted virtual disk storage map. The unmounted virtual disk may be mounted.
