  • Publication number: 20220085790
    Abstract: An acoustic resonator includes a piezoelectric stack including a piezoelectric layer having a top surface and a bottom surface, a top electrode layer disposed above the top surface, and a bottom electrode layer disposed below the bottom surface. A number of acoustic wave reflectors are disposed on a side of the bottom electrode layer opposite the piezoelectric layer. Each acoustic wave reflector includes a high acoustic impedance layer and may include a low acoustic impedance layer. The acoustic resonator may include a tether that extends laterally to a stacking direction of the layers of the piezoelectric stack. A supporting structure may be coupled to the tether opposite the acoustic resonator for anchoring the acoustic resonator. A mirror, one or more phononic crystals, or both may be positioned on proximate the tether opposite the acoustic resonator to avoid resonant waves from exiting the acoustic resonator in use.

  • Publication number: 20220075214
    Abstract: A high-power electro-optic modulator (EOM) is formed to use specialized electrodes of a material selected to have a CTE that matches the CTE of the modulator's crystal. Providing CTE matching reduces the presence of stress-induced birefringence, which is known to cause unwanted modulation of the propagating optical signal. The specialized electrodes are preferably formed of a CuW metal matrix composite having a W/Cu ratio selected to create the matching CTE value. Advantageously, the CuW-based electrodes also exhibit a thermal conductivity about an order of magnitude greater than conventional electrode material (brass, Kovar) and thus provide additional thermal stability to the EOM's performance.

  • Publication number: 20210404821
    Abstract: A network system dynamically determines a route, including start and end points, for vehicles in a transportation network. The transportation network receives a service request from a user of the transportation network including an origin location for the trip and a destination location for the trip. The transportation network then generates a waypoint plan for one or more vehicles, which includes the requested origin and destination in addition to any previously requested origins and destinations included in the vehicles current route. The network system then determines a directionality for each of the waypoints in the waypoint plan and retrieves candidate start and end points that have an associated directionality within a threshold angle of the directionality of each waypoint and are proximate to the waypoint. The network system evaluates each combination of retrieved candidate points to select a route for the vehicle.

  • Publication number: 20210359290
    Abstract: An immobilized chalcogen system or body includes an element of chalcogen, an electrically conductive material, and a hydrophilic membrane gate. The hydrophilic membrane gate may be used to isolate hydrophobic regions, one related to polychalcogenide ion(s) and another related to a hydrophobic electrolyte system. The hydrophilic membrane gate may prevent polychalcogenide from forming, and may provide control of undesirable parasitic mass transport and undesirable electron transport inside a chalcogen-based battery, and thereby allow the battery to cycle at a high specific capacity with a long cycling life. If desired, the immobilized chalcogen system or body may be employed in a cathode of a rechargeable battery.

  • Publication number: 20210349846
    Abstract: An embedded file network server based on a seismic data stream includes a broadband power management module, a main control unit, a serial-port-to-RS232 module, a PHY bridge layer, an SD card, and a network interface. The main control unit includes serial port, an SDIO interface, an internal RAM, DMA units, and a MAC drive layer. The main control unit performs seismic data interaction with an external device through the serial port, and receives seismic data through an internal interruption, and the received seismic data stream is stored in the internal RAM. The internal RAM transfers the received seismic data stream to the SDIO interface and MAC driver layer through the DMA units. The SDIO interface stores the seismic data stream in the SD card for data backup. The MAC driver layer is coupled to the PHY bridge layer for inputting and outputting the seismic data stream.
