Abstract: Methods for compensating for warpage in a semiconductor structure comprising an epitaxial layer grown on a semiconductor substrate. The methods include forming a buffer layer on the epitaxial layer and forming a compensating layer on the buffer layer; forming a buffer layer on the semiconductor substrate and forming a compensating layer on the buffer layer; and forming grooves in the epitaxial layer.

Abstract: An interrogator, methods of discerning the presence of an object, and interrogation systems employing the same. In one embodiment, the interrogation systems include multiple interrogators that communicate with a base command unit to track a location of an object. In another embodiment wherein the object is an RFID object (e.g., an object with an RFID tag), the interrogators employ signal processing techniques such as precharging the RFID object, and correlating a reference code with a reply code from the RFID object using selected techniques to increase a sensitivity of the interrogator, especially for adverse environments. In other embodiments, the interrogation systems include variations of metal instruments and sponges employed therewith. In yet another embodiment, the interrogation system includes metal interrogators capable of discerning the presence of a metal object, especially in a presence of another metal object.

Abstract: A patient support (10) is provided for supporting a patient. Patient support (10) includes a frame (12), a deck (16), a mattress (18) and siderails (24 and 26).

Abstract: A patient-support apparatus includes a patient-support deck movable from a use position to a stowed position. The patient-support deck is configured to engage receivers of the patient-support apparatus to support the deck in a cantilevered configuration. The patient-support deck may be secured to the patient-support apparatus by a locking mechanism. A storage structure is configured to support the patient-support deck in a stowed position. The storage structure is configured to deflect under load to prevent damage to the storage structure or patient-support deck.

Abstract: The present invention relates to a bed, in particular a hospital bed, fitted with a plurality of adjacent individual barrier elements along at least one of its longitudinal sides, the barrier elements extending vertically and each occupying a fraction of the length of the bed.

Abstract: A bandwidth monitor (14) monitors (21) the bandwidth of a transmission channel for a given wireless communication device (10), and a signal quality factor monitor (15) monitors (22) a signal quality factor relating to the wireless communication device's transmission. In response to the monitored factors, a transmission power setting unit (13) for the wireless communication device transceiver (12) typically adjusts (32) the transmission power for the wireless communication device (10) to maintain an essentially constant transmission power per unit bandwidth and to maintain an essentially constant signal strength as measured at the base station (11). Optionally, the transmission power is not increased if the signal quality factor exceeds a predetermined level or if the transmission power may fluctuate above the maximum transmission power for the wireless communication device (10).

Abstract: A carrier for an object having castors at each corner and a steering system comprised of a fixed pair of spaced steering wheels deployable to contact the surface proximate the midpoint of the carrier. The pair of steering wheels are separated by a distance that improves tracking of the carrier and allows the carrier to more easily be turned around corners. A linkage is connected between a foot pedal and the pair of steering wheels; and the pair of steering wheels is moved into surface contact simultaneously with said castors contacting the surface by pressing the foot pedal.
