Title: Descan compensation in scanning lidar
Inventor: REZK MINA
IPC: G01S7/481
Filed: 2019-09-20
Abstract: A light detection and ranging (LIDAR) apparatus is provided that includes a laser source configured to emit a laser beam in a first direction. The apparatus includes lensing optics to pass a first portion of the laser beam in the first direction toward a target, return a second portion of the laser beam into a return path as a local oscillator signal, and return a target signal into the return path. The apparatus also includes a quarter- wave plate to polarize the laser beam headed in the first direction and polarize the target signal returned through the lensing optics. The apparatus also includes a polarization beam splitter to pass non-polarized light through the beam splitter in the first direction and reflect polarized light in a second direction different than the first direction, wherein the polarization beam splitter further enables interference between the local oscillator signal and the target signal to generate a mixed signal. The apparatus also includes an optical detector to receive the mixed signal. In an embodiment, optical circuits 300 include multiple fiber outputs 302 and multiple optical detectors 304. The multiple fiber outputs 302 and optical detectors 304 may provide multiple data points during a single time interval. Accordingly, fewer rotations of fast scanning mirrors may provide additional data. For example, the optical circuits 300 may include a 1/4 wave plate 308 to polarize light, lensing 310 to provide reflected light, and the like. The alignment of the polarized beam splitter 306 may be set such that the fiber outputs 302 and optical detectors 304 are aligned when returned light is reflected. There may be multiple fiber outputs 302 and multiple optical detectors 304, but also multiple polarized beam splitters 306. The signals received at each of the optical detectors 304 may be analyzed separately to generate distance or velocity data at a point. The fiber outputs 302 may provide a laser beam at different wavelengths. Because the beams have interfered before the optical detectors and the detection path is decoupled from source path, the optical detectors can be larger core fibers or waveguides, silicon- based optical detectors, or other types of optical detectors that can sense the combined signal.

Title: Variable length piston assemblies for engine valve actuation systems
Inventor: BALTRUCKI JUSTIN
IPC: F01L13/06
Filed: 2019-10-04
Abstract: Variable-length assemblies, including lost motion assemblies eliminate hydraulic or pneumatic working fluids for operation in internal combustion engine valve trains and may be integrated into valve rocker arm pivots. An example piston and actuating plate are provided with working surfaces that interact when the actuating plate is rotated relative to the piston. The working surfaces include ramped transition portions and may include upper and lower flat portions. A shallow ramp angle prevents counter-rotation of the actuating plate under load. Actuating assemblies include an actuating solenoid includes a plunger that engages and pivots the actuating arm to cause rotation of the actuating plate relative to the piston and changes the state of the lost motion assembly from an "off state, where motion may be absorbed, to an "on" state where the lost motion assembly is rigid and does not absorb motion.
Patent WO-2020076774-A1 (WO)
Inventor: HIGGINS JOSEPH P
IPC: A61B17/32
Filed: 2019-10-08
Abstract: Devices, methods and systems are described that enable achieving a working diameter that is greater than a resting diameter and to stimulate fluid circulation during high-speed rotation. The drag coefficient of the drive shaft is increased and, in some embodiments, the mass is increased. Among other advantages, the resulting drive shaft with an eccentric element integrated with and/or attached thereto will achieve orbital motion at a rotational speed that is less the rotational speed required to achieve orbital motion without the increased drag coefficient. The concomitant increase in fluid flow and/or fluid stirring at a comparatively lower rotational speed is a further advantage. These characteristics may allow, therefore, a smaller diameter abrasive element to be used which is advantageous in small and/or highly tortuous vessels.

Title: Tungsten metal/tungsten nitride enhanced platinum-based orr catalyst and method for making the same
Inventor: WEIMER ALAN W
IPC: B01J23/18
Filed: 2019-10-25
Abstract: A method for forming an oxygen reduction reaction (ORR) catalyst (200, 900) may include providing a carbon (210, 910) supported platinum nanoparticle (220, 920) substrate (Pt/C) (110) and applying a tungsten nitride (WN) film (940) onto the surface of the Pt/C substrate (210, 220, 910, 920) using atomic layer deposition (ALD) (120). The Pt/C substrate (210, 220, 910, 920) with the WN film (940) may then be oxidized at a low temperature (130) and annealed at a high temperature in order to reduce WN to metallic tungsten (W) (140). The metallic W forms a blocking layer (230, 930) over coarse Pt nanoparticles (220, 920) and improves the activity and the durability of the Pt/C catalyst (900, 200) when used in fuel cells or related applications.

Abstract: A lazy updating system where a traditional non-blockchain database is updated first and applies a state change to a blockchain lazily while still allowing a client application to perform operations on the new state is disclosed. The lazy updating system enables transactions related to blockchain-based goods to use one or more databases (e.g., local or distributed databases) to mirror blockchain state. Operations such as displaying a user interface (Ul) with the current state of the blockchain use these databases instead of the blockchain directly to enable faster loading times. Instead of waiting for a blockchain to confirm a change to the state of their goods, the lazy updating system enables a service to first update its local database with a given change to allow users to interact with the new state and execute the blockchain transaction in the background with the assumption that the given change will eventually be confirmed.

Title: Activity detection in web applications
Inventor: VAN ROTTERDAM JEROEN MATTIJS
IPC: G06Q30/06
Filed: 2020-01-23
Abstract: A computing system includes a web server, client computing devices, a proxy between the web server and the client computing devices, and an analytics server. Each client computing device is operated by an end-user to access an application based on end-user events resulting in representational state transfer (REST) calls to the web server. The proxy passes through the REST calls to the web server and returns responses from the web server, with the return responses corresponding to activities being performed within the web application. The analytics server correlates the end-user events with the corresponding REST calls and return responses from the proxy for each client computing device, and uses vectorization to compare similar activities. The analytics server associates the similar activities with a quality indicator to identify anomalies within the application for corrective action to be taken.

Title: Architecture for usb-synchronized array of speakers
Inventor: BOROWSKI CHRISTOPHER IAN
IPC: H04R3/12
Filed: 2020-03-16
Abstract: A host device is connected via universal serial bus (USB) connections to one or more external devices with respective speakers. The host device synchronizes playback of audio through the speakers of the USB-connected external devices by requiring devices to implement a deterministic latency between receipt of a start playback request, and requiring devices to slave their audio clocks to USB start-of-frame tokens, and determining a buffered start time for starting data transmission to the respective USB devices. The buffered time equates to the current time of the USB host plus an additional time buffer. The host device waits until the buffered start time, and then starts transmitting the audio stream to the external devices, which, in turn, begin playing the audio data on the next available clock cycle, frame, or microframe.
