Abstract: The present invention provides a system, computer readable code and method for dynamically performing debugging. The system, code, and method store debugging logs throughout an operation. At predetermined points the logs are stored to a cache. Older and/or unnecessary logs are periodically deleted from the cache to ensure that the cache does not grow to be larger than a predetermined size. This avoids the need to re-run a scenario after an error occurs in order to produce troubleshooting/debugging information.

Abstract: The present invention discloses a computer-implemented method for engineering fluorinase enzymes towards the synthesis of fluorophenyl compounds. Limited or no mechanistic details of fluorinase enzymes have hindered progress in understanding their catalytic mechanisms for synthesizing synthetic organofluorine compounds. Through a comprehensive computational screening process, specific methionine-sulfonium phenyl substrates, including [(3S)-3-amino-3-carboxypropyl][2,5-difluoro-4-(4-methoxy-2,4-dioxobutyl)phenyl]methylsulfonium, were designed and optimized using quantum chemical optimization techniques. This methodology uncovers crucial information on F— ion attack conformation and the catalytic mechanism of the substrate, leading to the formation of Methyl 3-oxo-4-(2,4,5-trifluorophenyl)butanoate. Furthermore, a protein sequence and 3D modeling-based enzyme screening process was employed to identify the most suitable enzyme for this substrate.

Abstract: An eye tracking system comprising: a plurality of light sources that are arranged to illuminate a user's eye when the eye tracking system is in use; and a controller configured to: receive a first-image of a surface, acquired while the surface is illuminated by a first set of the plurality of light sources; receive a second-image of the surface, acquired while the surface is illuminated by a second set of the plurality of light sources, wherein the second set of light sources is different to the first set of light sources; process the first-image and the second-image to determine an illumination contribution of one or more of the light sources; and determine light-source-control-signaling for one or more of the light sources based on the determined illumination contribution of the one or more of the light sources.

Abstract: A method of operation of a flash integrated circuit (IC) memory device is described. The flash IC memory device has an array of memory cells and an interface to receive control, address and data signals using an internal reference voltage. The method includes, at boot-up, initializing the internal reference voltage to a default voltage. At boot-up, the interface is operable to receive, using the internal reference voltage, signals having a first voltage swing at a first signaling frequency. The method includes receiving a first command that specifies calibration of the interface during a calibration mode. The calibration mode is used to calibrate the interface to operate at a second signaling frequency and receive signals having a second voltage swing. The second voltage swing is smaller than the first voltage swing and the second signaling frequency is higher than the first signaling frequency.

Abstract: Described herein are systems and methods that detect an electromagnetic signal in a constant interference environment. In one embodiment, the electromagnetic signal is a light signal. A constant interference detector may detect false signal “hits” generated by constant interference, such as bright light saturation, from valid signals. The constant interference detector determines if there is constant interference for a time period that is greater than a time period of the valid signal. In one embodiment, if a received signal exceeds a programmable threshold value for a programmable period of time, when compared to previously stored ambient light, a control signal is generated to inform the next higher network layer of a sudden change in ambient light. This control signal can be used to either discard the present return or process the signal in a different way. A constant interference detector may be a component of a LIDAR system.

The receiver is configurable with dual-mode I/O support to operate the CA bus in a low-swing mode and a high-swing mode. The receiver is configurable to receive a first command on the I/O pin while in the high-swing mode, initiate calibration of the slave device to operate in the low-swing mode in response to the first command, switch the slave device to operate in the low-swing mode while the CA bus remains active, and to receive a second command on the I/O pin while in the low-swing mode.

Abstract: LIDAR measurement systems employing a multiple channel, GaN based illumination driver integrated circuit (IC) are described herein. In one aspect, the multiple channel, GaN based illumination driver IC selectively couples each illumination source associated with each measurement channel to a source of electrical power to generate a measurement pulse of illumination light. In one aspect, each pulse trigger signal associated with each measurement channel is received on a separate node of the IC. In another aspect, additional control signals are received on separate nodes of the IC and communicated to all of the measurement channels. In another aspect, the multiple channel, GaN based illumination driver IC includes a power regulation module that supplies regulated voltage to various elements of each measurement channel only when any pulse trigger signal is in a state that triggers the firing of an illumination pulse.

Abstract: An apparatus includes a memory and processor. The memory stores previous requests and corresponding previous responses. The processor determines that a user device transmitted a new voice request, converts the voice request into a first set of text, and transmits the text to an agent device. The processor applies the machine learning algorithm to the first set of text to generate suggested responses, by identifying patterns shared by the first set of text and a subset of the previous requests that are associated with the suggested responses. The processor transmits the suggested responses to the agent device. The processor then determines that the agent device transmitted voice signals responding to the new request. The processor converts these voice signals into a second set of text. The processor stores the first set of text as a previous request, and the second set of text as a corresponding previous response.

Abstract: Methods and systems for performing three dimensional LIDAR measurements with an integrated LIDAR measurement device are described herein. In one aspect, a return signal receiver generates a pulse trigger signal that triggers the generation of a pulse of illumination light and data acquisition of a return signal, and also triggers the time of flight calculation by time to digital conversion. In addition, the return signal receiver also estimates the width and peak amplitude of each return pulse, and samples each return pulse waveform individually over a sampling window that includes the peak amplitude of each return pulse waveform. In a further aspect, the time of flight associated with each return pulse is estimated based on a coarse timing estimate and a fine timing estimate. In another aspect, the time of flight is measured from the measured pulse due to internal optical crosstalk and a valid return pulse.

Abstract: The present disclosure relates generally to systems and methods for configuring architectures for a sensor, and more particularly for light detection and ranging (hereinafter, “LIDAR”) systems based on ASIC sensor architectures supporting autonomous navigation systems. Effective ASIC sensor architecture can enable an improved correlation between sensor data as well as configurability and responsiveness of the system to its surrounding environment and avoid any unnecessary delay within the decision-making process that may result in a failure of the autonomous driving system. It may be essential to integrated multiple functions within an electronic module and implement the functionality with one or more ASICs.

Abstract: Systems and methods for detecting blockages for light detection and ranging (“LiDAR”) devices are disclosed. According to one embodiment, a light detection and ranging (LiDAR) blockage detection method includes emitting, by an active channel of a plurality of channels of a LiDAR device, an optical signal toward a configured position on a housing of the LiDAR device. A passive listening channel of the plurality of channels receives a return signal originating from the optical signal. Based on a comparison of data derived from the return signal and data derive from a reference signal, a determination is made as to whether a blockage is present at the configured position on the housing.

Abstract: Images of an eye are captured by a camera. For each of the images, gaze data is obtained and a position of a pupil center is estimated in the image. The gaze data indicates a gaze point and/or gaze direction of the eye when the image was captured. A mapping is calibrated using the obtained gaze data and the estimated positions of the pupil center. The mapping maps positions of the pupil center in images captured by the camera to gaze points at a surface, or to gaze directions. A further image of the eye is captured by the camera. A position of the pupil center is estimated in the further image. Gaze tracking is performed using the calibrated mapping and the estimated position of the pupil center in the further image. These steps may for example be performed at a HMD.

Abstract: An eye tracking system includes at least two cameras configured to register eye images of at least one eye. The system obtains eye images from at least one camera in a subset of the at least two cameras, determines a first pupil parameter based on a first eye image, and determines a second pupil parameter based on a second eye image. The system compares the first and second pupil parameters to obtain a test parameter and checks the test parameter against at least one operation criterion. Responsive to the checking, the system assigns a respective operation state to at least one camera in the subset. The operation state involves one of (A) operating the camera at a high frame rate, (B) operating the camera at a reduced frame rate being lower than high frame rate, (C) the camera being in a standby mode or (D) the camera being powered off.
