Abstract: A portion of a source mixed reality (MR) experience is retrieved. Then, the portion of the source MR experience is used to generate a serialized representation including a hierarchy of tagged elements. The hierarchy of tagged elements includes a plurality of MR step elements collectively defining a procedure to be performed by a viewer of an MR experience. Each MR step element has child elements that include an MR step number indicating a position of the MR step in the MR procedure and an MR step ID element indicating an identity of the MR step. The serialized representation is deserialized to generate a portion of a target MR experience to be edited in an MR development tool. The portion of the target MR experience is usable to cause each MR step in the plurality of MR steps to be graphically represented in the MR development tool.

Abstract: A facility for providing an XR device-based tool for cross-platform content creation and display is disclosed. The facility causes a definition of a mixed reality (MR) procedure to be presented by an editing MR device in a virtual application window. Input is received via the editing MR device. The facility interprets the received input as one or more editing actions performed with respect to the MR procedure definition and alters the MR procedure definition accordingly. The facility creates a device-independent representation of the MR procedure based on the altered MR procedure definition.

Abstract: Techniques for developing mixed reality applications in connection with a virtual development environment are disclosed. A reference model corresponding to a physical object is received. Then, the reference model is displayed in a virtual development environment. First input arranging an anchor with the reference model in the virtual development environment is received.

Abstract: A method of making generally symmetrical lamination stacks for electrical machines comprises producing generally symmetrical pole tips from alternating asymmetrical pieces that each have an additional layer in the asymmetrical portion. With the alternating asymmetrical pieces combined, the resulting pole tip is generally symmetrical with a larger possible pole tip width compared with currently-used interleaved stamping techniques.

Abstract: A micro-hotplate is provided in the form of a device comprising a sensor and one or more resistive heaters within the micro-hotplate arranged to heat the sensor. Furthermore a controller is provided for applying a bidirectional drive current to at least one of the heaters to reduce electromigration. The controller also serves to drive the heater at a substantially constant temperature.

Abstract: A micro-hotplate is provided in the form of a device comprising a sensor and one or more resistive heaters within the micro-hotplate arranged to heat the sensor. Furthermore a controller is provided for applying a bidirectional drive current to at least one of the heaters to reduce electromigration. The controller also serves to drive the heater at a substantially constant temperature. Such an arrangement is advantageous over an arrangement in which a unidirectional DC drive current is applied to the heater. This is because the unidirectional drive current causes electromigration which results in an increase in resistance over time. This is undesirable because it can lead to failure of the micro-hotplate. In contrast, the application of the bidirectional current reduces electromigration and as a result there is insignificant change in the resistance of the heater over time and under high temperature.

Abstract: A gas-sensing semiconductor device is fabricated on a silicon substrate having a thin silicon oxide insulating layer in which a resistive heater made of a CMOS compatible high temperature metal is embedded. The high temperature metal is tungsten. The device includes at least one sensing area provided with a gas-sensitive layer separated from the heater by an insulating layer. As one of the final fabrication steps, the substrate is back-etched so as to form a thin membrane in the sensing area. Except for the back-etch and the gas-sensitive layer formation, that are carried out post-CMOS, all other layers, including the tungsten resistive heater, are made using a CMOS process employing tungsten metallisation. The device can be monolithically integrated with the drive, control and transducing circuitry using low cost CMOS processing. The heater, the insulating layer and other layers are made within the CMOS sequence and they do not require extra masks or processing.

Abstract: A method and system for optimizing a configuration of mediation devices in a telecommunications central office. Specifications associated with mediation devices are provided. A configuration of mediation devices and legacy devices in a central office is generated. A specification is compared to an attribute of a mediation device in the configuration. The attribute is one of: (1) a distance between the mediation device and a legacy device to be connected to the mediation device, (2) an amount of data to be received by the mediation device from one or more legacy devices to be connected to the mediation device, and (3) a count of one or more legacy devices to be connected to the mediation device. The configuration is updated in response to the comparing of the specification to the attribute. The updating of the configuration provides an optimized number of mediation devices.

Abstract: A scatterometer orbiting around the earth globe comprises a single fanbeam radar antenna which is rotated around a vertical axis, at a slow rotation rate. The antenna foot-print sweeps a circular disc. The slow conical sweep combined with the motion of the satellite on which the scatterometer is mounted results in highly overlapping successive sweeps such that an image pixel is revisited many times during an overpass. The pixels in the radial direction are resolved by range-gating the radar echo. The radar operates in the C-band. The scatterometer is intended, in particular, to determine wind speed and direction over the ocean.
