Abstract: The present disclosure provides a new series of compounds exhibiting high fluorescence quantum yields in the solid state. In one embodiment, the compounds include a series of 2,3,4,5-tetraphenylgermoles with the same or different 1,1-substituents. In another embodiment, substituted germafluorenes, germa-fluoresceins/rhodamines, and germapins are described. These germanium heterocycles possess ideal photophysical and thermostability properties, which makes them excellent candidates for chemical or biological sensors, host materials for electroluminescent devices and solar cells, and emissive and/or electron-transport layer components in organic light emitting diode devices.

Abstract: A method of removing an ophthalmic lens from a lens mold portion is provided and includes reciprocally displacing a region of the mold portion and thereby causing an edge portion of the ophthalmic lenses to become detached from the mold portion. Related apparatus, methods of manufacturing ophthalmic lenses, delensing stations, and manufacturing times are provided.

Abstract: Apparatus and methods are described for manufacturing contact lenses by forming a contact lens mold half, and removing the mold half. The mold half can then be combined with a complementary mold half and used to cast-mold a contact lens. The apparatus includes first and second plates each carrying tool halves. The plates reciprocate between an open, spaced apart configuration, and a closed configuration in which they hold complementary tool halves in contact with one another. When the plates are opened after forming a mold half, a gripper plate removes the mold half from the first plate or the second plate.

Abstract: Methods, devices, and systems are used for a vehicle user interface adaption system. In an example, operations may be effectuated that include displaying a graphical user interface including a first plurality of objects associated with a first unmanned aerial vehicle and receiving data that includes a message from the graphical user interface indicative of a selection of a second unmanned aerial vehicle. A second plurality of objects may be displayed based on the received data.

Abstract: Methods and apparatus for exchanging tools and/or tool assemblies used to form different types of molds for in injection-molding machines, are described. The exchange of tools and/or tool assemblies is made using a robot. Contact lens mold halves and assemblies for molding contact lenses of different powers or types can be made with a single injection-molding apparatus.

Abstract: Packaged integrated circuit devices include an oscillator circuit having a resonator (e.g., quartz crystal, MEMs, etc.) associated therewith, which is configured to generate a periodic reference signal. A built-in self-test (BIST) circuit is provided, which is selectively electrically coupled to first and second terminals of the resonator during an operation by the BIST circuit to test at least one performance characteristic of the resonator, such as at least one failure mode. These test operations may occur during a built-in self-test time interval when the oscillator circuit is at least partially disabled. In this manner, built-in self-test circuitry may be utilized to provide an efficient means of testing a resonating element/structure using circuitry that is integrated within an oscillator chip and within a wafer-level chip-scale package (WLCSP) containing the resonator.

Abstract: A bistatic radar system may include a transmitter, a target at a first known position, a receiver at a second known position, and a transmitter position determination unit. The receiver is configured to receive one or more reflected radar signals transmitted from the transmitter and reflected off the target. The receiver is configured to receive one or more direct radar signals transmitted from the transmitter. The transmitter position determination unit is configured to determine a position of the transmitter based on a determination of a distance between the first and second known positions and a determination of a first angular difference between the reflected radar signal(s) and the direct radar signal(s) that are received by the receiver.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing filtered backups of a distributed database. One of the methods includes receiving a user request to generate an incremental backup to be added to a user specified backup sequence for a distributed database, wherein the user specified backup sequence specifies a subset of one or more database tables to be included in backups in the user specified backup sequence. Dirty partitions of the one or more tables covered by the user specified backup sequence are identified, wherein a dirty partition is a table partition that was created or modified after generation of a most recent backup in the user specified backup sequence. An incremental backup to be added to the user specified backup sequence is generated, the incremental backup comprising contents of the dirty partitions of the tables covered by the user specified backup sequence.

Abstract: A signal processing method is provided. The signal processing method includes receiving, at a signal processing system, a signal of interest, calculating, using the signal processing system, a power spectral density for the signal of interest, calculating, using the signal processing system, a basis vector based on the power spectral density shape, performing, using the signal processing system, a linear regression using the basis vector to generate an estimate for at least one parameter of the signal of interest, and transmitting, based on the at least one generated estimate, a signal that avoids interference with the signal of interest.
