Abstract: A light carrier for engaging a surgical tube includes unitarily and communicably interconnected inlet, intermediate and channel sections composed of a light conducting material. The channel section is laterally concave and has a light projecting surface portion. The channel section is introduced into the surgical tube and light introduced through the inlet section is transmitted through the light carrier and projected into the tube to illuminate a medical or surgical procedure being performed through the tube.

Abstract: Techniques and mechanisms for providing power telemetry information which indicates a total load current from one or more power supply units (PSUs). In an embodiment, a device is coupled to receive a first signal from the current share bus which is coupled to each of multiple PSUs. A voltage level of the first signal represents a target amount of current to be output by each of the one or more PSUs. A second signal is generated based on both the first signal, and on an indication of a scale according to which a primary PSU of the one or more PSUs represents a target amount of current. In another embodiment, an amplification is performed, based on the second signal and on a total number of the one or more PSUs, to generate an Isys signal which indicates a total load current output by the one or more PSUs.

Abstract: Non-destructive localization of open defects in electronic devices is performed with a DC SQUID based RF magnetometer capable of sensing coherent magnetic fields up to 200 MHz and higher. RF magnetic fields (or RF current) images are correlated to conductive paths layout of the electronic device, and the open defect is pinpointed at a location of RF current disappearance on the current image. The bandwidth limitations associated with transmission line delays between SQUID circuit and readout electronic, as well as with near-field coupling between different parts of the measurement scheme, are overcome by superimposing the RF flux emanating from device under study on the modulation flux to produce at the SQUID output a binary phase modulated RF voltage, which is processed to lock the static flux, and to control modulation regime by producing an AC bias for the RF flux.

Abstract: An RF DC SQUID based magnetometer capable of sensing coherent magnetic fields up to 200 MHz and higher is developed which overcomes frequency limitations associated with noise signals due to transmission line delays between the SQUID circuit and readout electronics. The bandwidth limitations are overcome by superimposing the RF flux on the modulation flux to produce at the SQUID output a binary phase modulated RF voltage, which is processed to lock the static flux, and to control modulation regime by producing an AC bias for the RF flux. RF readout electronics based on a double lock-in technique (sequential demodulation of the RF SQUID voltage at the modulation flux frequency ?m and the RF flux frequency ?RF), yields a signal proportional to the product of amplitude and phase cosine of RF flux with linear dynamic range up to five orders in magnitude if compared to DC SQUID operated in traditional flux-locked loop regime.

Abstract: Methods, systems, and computer-readable and executable instructions are provided for resource planning. Resource planning can include identifying a resource capacity for a given resource planning horizon, identifying a resource pool guideline that defines a priority of resources from which to satisfy a full-time equivalent (FTE) resource planning requirement, and performing resource planning by satisfying the FTE requirement based on the resource capacity and the resource pool guideline.

Abstract: Headgear for mounting a headlight on a surgeon's head includes a headband and a stabilizer. The headband encircles the wearer's head and the stabilizer is connectable to a rear section of the headband for engaging and cradling a substantial portion of at least a lower back region of a wearer's head when the headgear is worn by the wearer. The stabilizer includes a peripheral extending portion extending beneath the headband on opposite sides of the wearer's head corresponding to a location of a lower portion of an occipital bone of the wearer's head and a peripheral portion extending above the headband on opposite sides of the wearer's head corresponding to a location of a top of the occipital bone. The headgear can also include a connection element for removably connecting the stabilizer to the headband so that the headgear can be worn with or without the stabilizer.

Abstract: Circuit flaws in microelectronic circuitry present regions of high resistance in which a current distribution deviates from that of a defect-free circuit. The altered current distribution emits a correspondingly altered magnetic field in accordance with Ampere's Law. When compared with the magnetic field of a defect-free circuit, the anomaly in the magnetic field of the defective device is detected and the location of the circuit flaw may be determined therefrom. As the anomaly in the magnetic field is very small in magnitude, a sensitive magnetic microscope is utilized to obtain images of the magnetic fields of a defect-free reference device and a device-under-test. The distance between the magnetic sensor and the devices being scanned is precisely controlled to minimize influences of scanning distance on the difference in measured magnetic field strength. Comparative image analysis reveals the location of the circuit flaw.
