Abstract: The large-scale artificial synaptic device arrays based on the organic molecule-nanowire heterojunctions with tunable photoconductivity are proposed and demonstrated. The organic thin films of p-type 2,7-dioctyl[1]benzothieno[3,2-b][1] benzothiophene (C8-BTBT) or n-type phenyl-C61-butyric acid methyl ester (PC61BM) are used to wrap the InGaAs nanowire parallel arrays to configure two different type-I heterojunctions, respectively. Due to the difference in carrier injection, persistent negative photoconductivity (NPC) or positive photoconductivity (PPC) are achieved in these heterojunctions. The irradiation with different wavelengths (solar-blind to visible ranges) can stimulate the heterojunction devices, effectively mimicking the synaptic behaviors with two different photoconductivities. Evidently, these photosynaptic devices are illustrated with retina-like behaviors and capabilities for large-area integration, which reveals their promising potential for artificial visual systems.

Abstract: A method of fabricating semiconducting tellurium (Te) nanomesh. The method includes the steps of preparing a substrate, vaporizing Te powders under a first temperature; and growing Te nanomesh on the substrate using the vaporized Te powders under a second temperature. The first temperature is higher than the second temperature. The rationally designed nanomesh exhibits exciting properties, such as micrometer-level patterning capacity, excellent field-effect hole mobility, fast photoresponse in the optical communication region, and controllable electronic structure of the mixed-dimensional heterojunctions.

Abstract: An audio processing device comprises audio input circuitry operable to receive audio input signals and to process the audio input signals to generate audio samples at a first rate. The audio processing device further comprises a first trigger engine operable to detect a keyword within the audio samples. Also, the audio processing device comprises a delay buffer operable to continuously receive and store the audio samples. The delay buffer is further operable to transfer the audio samples that are stored within the delay buffer to a host across a data bus at a second rate, which is faster than the first rate. Further, the delay buffer is operable to transfer the audio samples that are stored within the delay buffer to the host at the first rate, after the stored audio samples are transmitted.

Abstract: The bike's crank speed and crank position are sensed via a micro controller, torque sensor, gyro and accelerator disposed on the bike's crank. External power and control signals can be passed to and from the crank micro controller and the e-bike controller through a throttle connector of the e-bike controller via slip rings around the crank hub with and with pogo pin connectors connected to the respective slip rings. Throttle data can also be provided to the e-bike controller wirelessly via a wireless dongle coupled to the throttle connector of e-bike controller.

Abstract: A tray for use in a car trunk includes a main body, and several gripping elements; the main body has a circumferential wall, and several connecting protrusions thereon, and it is firmly held in a car trunk with the circumferential wall touching an inner side of the trunk; each of the gripping elements has at least one connecting hole on a lower end thereof; the gripping elements are connected to the main body in a relocatable manner with the connecting protrusions being fitted in the connecting holes, such that said gripping elements are pressed against circumferential sides of objects supported on the main body to hold the objects steady.

Abstract: An automated soldering system includes a robotic soldering machine and a plurality of feed lines for delivering workpieces to be soldered by the soldering machine. Each of the feed lines transports workpieces such as LCD modules from an input end to a soldering area, and from the soldering area to an outlet end. The soldering areas are arranged within the range of motion of a soldering arm of the soldering machine are preferably arranged in a bilateral triangle having the pivot axis of the soldering are at its apex. The soldering arm is programmed to work reciprocally among the soldering areas, thus increasing the yield of the robotic soldering machine so that the soldering machine is more cost effective. The soldering machine may be programmed to perform different soldering operations at different soldering areas.

Abstract: To determine the number of bits to encode a current audio frame, in accordance with a running average of the common scale factors for all preceding audio frames, a common scale factor for the-current frame is computed. The current frame is encoded using the computed common scale factor if the same falls within a defined range, and the number of bits required to so encode the frame also falls within a calculated range. If, the number of bits required to so encode the frame falls outside the calculated range, an energy level associated with the current frame and a running average of the energies of all previous frames is computed, which in turn, are used to compute a target bit rate. Thereafter, a common scale factor which results in coding of the current frame using a number of bits close to the target bit rate is obtained.

Abstract: A double deck wheel cover includes an inner part, and an outer part. The inner part is detachably fitted on a central portion of a wheel. The outer part has spaced connecting plates projecting from the inner side through corresponding slots of the inner part. Tension springs are connected to the connecting plates at outer ends. Inner ends of the springs are connected to a steel ring secured to the inner part. The outer part has a larger diameter than the outer part so that an outer edge thereof covers a portion of a lateral side of a tire joined to the wheel, thus reducing thickness of visible portion of the tire lateral side to make the tire to look like a sport tire that has a relatively low aspect ratio, i.e. the proportion of the thickness of the lateral portion to the width of the tread of the tire.
