Abstract: The detection of a use status of an object. To ascertain the use status, i.e., the decision as to whether or not an object is presently in use, using sensor data of multiple sensors provided at the object. For this purpose, in particular, the individual results about the use status may be correlated with one another. When needed, additional sensors may be activated and incorporated in the evaluation.

Abstract: There is disclosed a method and a device connected to a serial bus, said method comprising transmitting a message that indicates a power requirement for a suspended mode of said serial bus; in response to a received authorization message, setting a first or a second operating state; entering said suspended mode; drawing a current in accordance with said indicated power requirement that may exceed a predetermined current limit if said operating state is said first state, and drawing a current at or below said predetermined current limit if said operating state is said second state.

Abstract: In the case of a universal serial bus (USB) connection, a host detects a connection of a peripheral to the host via a USB interface of the host. The host then generates an informative command, which includes information on capabilities of the host. This informative command is provided for transmission via the USB interface to the peripheral. The peripheral receives the informative command and may for instance evaluate the included information for selecting a suitable USB mode that is to be entered or for deciding on becoming a host itself. Alternatively or in addition, the host may generate a request command for retrieving information on all classes offered in all USB modes of a peripheral.

Abstract: A therapy utilizing inhaled anesthetic agents (such as desflurane, sevoflurane, isoflurane, or xenon) for the sedation of patients outside of the immediate perioperative space such as in the medical intensive care unit (MICU) and the surgical intensive care unit (SICU). The therapy includes controlled delivery of volatile anesthetic agents to patients undergoing ventilatory support on an ICU ventilator over extended periods of time. A system which provides for the delivery of anesthetic agents includes an anesthetic agent vaporizer element, an anesthetic agent reflector, and a plug-in cassette which contains both a cartridge housing liquid phase volatile anesthetic agent and an anesthetic vapor scrubbing medium.

Abstract: A slave low power radio frequency transceiver participates in a network controlled by a master low power radio frequency transceiver and synchronises its timing to the network timing by receiving radio packets transmitted from the controlling low power radio frequency transceiver. The slave transceiver comprises timing means; detection means operable over an interval of time for detecting a predetermined portion of a received radio packet; and adjusting means for adjusting the timing means in response to the detection of a predetermined portion of a received radio packet. The slave low power radio frequency transceiver is arranged to controllably vary the duration of the interval of time.

Abstract: Systems and methods are provided for communication between master and slave devices on a network, such as a piconet or Bluetooth network. A master notifies the slave of a change in the link supervision timeout associated with the piconet. The slave stores the new link supervision timeout value and uses this value to control subsequent network-related operations, such as inquiry and paging procedures within a scatternet. The slave, aware of the link supervision timeout value for its existing connection may set an activity time limit for procedures in order to return to the physical channel of the piconet before a timeout connection loss to reestablish contact with the piconet master.

Abstract: A method and system for compensating for misalignment of a piece of target material to which a design is to be applied is described. One embodiment receives first and second sets of coordinates corresponding to the location, respectively, of first and second reference points on the target piece of material; modifies, based on the received first and second sets of coordinates, design data that specifies a predetermined position and orientation of the design on the target piece of material with respect to the first and second reference points to produce modified design data, the modified design data compensating for at least one of translational and rotational misalignment of the target piece of material with respect to a design-application mechanism; and applies the design to the target piece of material in accordance with the modified design data.

Abstract: A low power radio frequency transceiver is arranged to form a network of communicating low power radio frequency transceivers. It comprises a transmitter for transmitting packets of data and means for controlling the transmitter to transmit a series of messages of a first type outside the network of transceivers, for maintaining synchronisation.

Abstract: Systems and methods applicable, for example, in connection functionality. A device might, for instance, provide connection to one or more services via one or more devices. The device might, for example, detect a device offering one or more of those services. The device providing connection might, for instance, consider one or more priorities, connection disruption indications, and/or connection maintenance indications. The device providing connection might, for example, stop providing connection via one or more of the devices via which connection was being provided, and/or might start providing connection via the detected device.

Abstract: An antiferromagnetically exchange-coupled structure for use in a magnetic device, such as a magnetoresistive sensor, includes an underlayer formed of a chemically-ordered tetragonal-crystalline alloy, a chemically-ordered tetragonal-crystalline Mn-alloy antiferromagnetic layer in contact with the underlayer, and a ferromagnetic layer exchange-coupled with the antiferromagnetic layer. The underlayer is an alloy selected from the group consisting of alloys of AuCu, FePt, FePd, AgTi3, Pt Zn, PdZn, IrV, CoPt and PdCd, and the antiferromagnetic layer is an alloy of Mn with Pt, Ni, Ir, Pd or Rh. The underlayer enhances the transformation of the Mn alloy from the chemically-disordered phase to the chemically-ordered phase.
