摘要： A stress-isolated microelectromechanical systems (MEMS) device and a method of manufacture of the stress-isolated MEMS device are provided. MEMS devices may be sensitive to stress and may provide lower performance when subjected to stress. A stress-isolated MEMS device may be manufactured by etching a trench and/or a cavity in a first side of a substrate and subsequently forming a MEMS device on a surface of a platform opposite the first side of the substrate. Such a stress-isolated MEMS device may exhibit better performance than a MEMS device that is not stress-isolated. Moreover, manufacturing the MEMS device by first forming a trench and cavity on a backside of a wafer, before forming the MEMS device on a suspended platform, provides increased yield and allows for fabrication of smaller parts, in at least some embodiments.

摘要： One embodiment is a method of performing thoracic tomography on a human subject including performing multiple 4-wire impedance measurements on a region of interest to obtain measured impedance data; comparing the measured impedance data to simulated impedance data obtained from a plurality of models of the region of interest; for each of the models, determining a fit of the model based on a comparison between the simulated impedance data obtained from the model and the measured impedance data; and integrating individual resistivity estimates obtained from the models based on a fit of the model such that the individual resistivity estimate from a better fitting model is weighted more heavily in a final resistivity estimate than an individual resistivity estimate from a worse fitting model.

摘要： An automated testing system comprises a high side switch circuit coupled to an input/output (I/O) connection, a low side switch circuit coupled to the I/O connection, a high side force amplifier (HFA) coupled to the high side switch, a low side force amplifier (LFA) coupled to the low side switch, an adjusting circuit coupled to the HFA and the LFA, and a control circuit configured to change the adjusting circuit to change control of current at the I/O connection from one of the HFA or LFA to the other of the HFA or LFA.

摘要： Far field devices typically rely on audio only for enabling user interaction and involve only audio processing. Adding a vision-based modality can greatly improve the user interface of far field devices to make them more natural to the user. For instance, users can look at the device to interact with it rather than having to repeatedly utter a wakeword. Vision can also be used to assist audio processing, such as to improve the beamformer. For instance, vision can be used for direction of arrival estimation. Combining vision and audio can greatly enhance the user interface and performance of far field devices.

摘要： The present disclosure provides a method of fabricating a target capture and sensor assembly. The method comprises the steps of: providing a fluid path with a target capture surface comprising an anchor species with a first functional group disposed thereon; providing a target capture species to the target capture surface of the fluid path, wherein each target capture species comprises a target capture part and a second functional group configured to react with the first functional group; and exposing at least a portion of the target capture surface of the fluid path to photo radiation so as to cause a photo-initiated reaction between the first functional group and the second functional group, wherein the target capture and sensor assembly further comprises a sensing surface in the fluid path and wherein the target capture surface and the sensing surface are in fluid communication with one another.

摘要： System and apparatus for robust, portable gas detection. Specifically, this disclosure describes apparatuses and systems for optical gas detection in a compact package using two optical pathways. There is a need for a very compact, low-power, gas detection system for gases such as CO2, NOx, water vapor, methane, etc. This disclosure provides an ultra-compact and highly stable and efficient optical measurement system based on principals of optical absorption spectroscopy using substantially collinear pathways.

摘要： A system for gas sensing of a biological specimen can include a chamber, such as to receive the biological specimen therewithin. The system can also include a gas sensing unit to be coupled to the chamber and separated therefrom by a moveable separator. A gas sensor included in the gas sensing unit can be selectively exposed to a fluid headspace of the first chamber, such as a gas environment associated with the biological specimen, upon modification or moving of a separator.

摘要： A network node device of an area network includes physical layer (PHY) circuitry configured to transmit and receive frames of data via a communication link of the communication network; medium access layer (MAC) circuitry; a receive interface between the PHY circuitry and the MAC circuitry, and timestamp circuitry. The receive interface includes a receive clock signal and a DLL. The timestamp circuitry is configured to produce multiple sample signals derived from the receive clock signal using the DLL and a local clock signal of the network node, and produce a timestamp offset using the multiple sample signals. The timestamp offset is representative of an instantaneous phase offset between a local clock of the network node and a local clock of a neighbor node of the network node.
