摘要:
Commercial material processing machines such as garment laundering often entail conveyors and large containers (e.g., dryer drum, washer) that pose safety hazards to workers who work in proximity to the equipment, even safety procedures if followed would preclude the worker from inadvertently entering the machine. Having an interrogator antenna within the machine and a transmitter attached to the worker, such as a Radio Frequency Identification (RFID) tag provides a means for sensing when a worker is in a hazardous position. When sensed, safety circuitry shuts off actuators to prevent further conveying of material into the machine and movement of the large container (e.g., drum).

A method for processing garments. Soiled garments corresponding to a route are received and washed. The garments are configured for processing and stored based on the route. From storage, the garments may be transferred to a sorter and sorted based on a determined sequence within the route, transferred to a repair station, transferred to a steaming station or transferred to a delivery vehicle for delivery. After sorting, repairing or steaming, the garments may be conveyed back to storage or loaded onto a delivery vehicle for delivery. Also, from storage, garments may be added or removed from the route and the garments may be sorted or re-sorted based on the new number of garments in the route.

A control circuit of a surgical device is disclosed. The control circuit includes a first circuit portion coupled to at least one switch operable between an open state and a closed state. The first circuit portion communicates with a surgical generator over a conductor pair to receive a control signal to determine a state of the at least one switch.
摘要:
An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein one or both of the first and second jaws can include a plurality of electrodes each comprised of a positive temperature coefficient material having a different switching temperature. The electrical resistances of the electrodes can increase significantly once the temperature of the electrodes exceed their switching temperatures and, owing to the increased electrical resistance, the flow of current through the electrodes can be reduced and/or prevented. In various circumstances, the different switching temperatures of the electrodes can allow some of the electrodes to switch off before the other electrodes.

In accordance with various embodiments, a surgical generator for providing a drive signal to a surgical device may comprise a first transformer and a second transformer. The first transformer may comprise a first primary winding and a first secondary winding. The second transformer may comprise a second primary winding and a second secondary winding. The surgical generator may further comprise a generator circuit to generate the drive signal. The generator circuit may be electrically coupled to the first primary winding to provide the drive signal across the first primary winding. The surgical generator may also comprise a patient-side circuit electrically isolated from the generator circuit. The patient-side circuit may be electrically coupled to the first secondary winding. Further, the patient-side circuit may comprise first and second output lines to provide the drive signal to the surgical device. In addition, the surgical generator may comprise a capacitor. The capacitor and the second secondary winding may be electrically coupled in series between the first output line and ground.
摘要:
An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein at least one of the electrodes can comprise a conductive material positioned within a non-conductive, or high-resistance, material. In use, current flowing through the conductive material can heat the conductive material and cause it to evaporate and leave behind the non-conductive material. In such circumstances, the current flowing through the electrode may cease or may be substantially reduced.
摘要:
A process for laundering, sorting and delivering garments is enhanced by incorporating a Radio Frequency IDentification (RFID) tag into each garment. An RFID reader antenna includes left and right interleaved parallel and vertically aligned pluralities of generally orthogonal ferrite horseshoes to shape the sensing magnetic fields. The span of coverage along with the non-aligned magnetic fields ensure that RFID tag is read even regardless of orientation. Accurate detection facilitates tracking of garments during laundering, repair, replacement, sorting, etc.

A process for laundering, sorting and delivering garments is enhanced by incorporating a radio frequency identification RFID) tag into each garment. An RFID reader antenna includes left and right interleaved parallel and vertically aligned pluralities of orthogonal ferrite horseshoes to shape the sensing magnetic fields. An encryption scheme gives anonymity to the wearer of the garment.
摘要:
A tissue thickness compensator may generally comprise a biocompatible material, a first component, and a second component, wherein the first component and second component form a reaction product to expand the tissue thickness compensator. The first component may comprise a first hydrogel precursor, the second component may comprise a second hydrogel precursor, and the reaction product may comprise a hydrogel. The reaction product may be formed in vivo and/or in situ by contacting the first component and the second component. The first component and/or second component may be encapsulated and configured to release the components when ruptured. The reaction product may comprise a fluid-swellable composition. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.
