Abstract: A window shutter for securing windows. The window shutter comprises at least one first shutter and at least one second shutter. The first shutter is coupled to the second shutter via hinges. The first shutter is affixed to a wall and adjacent to a window frame. The second shutter is operable to swing about a pivot axis of the hinges. The second shutter is used to secure windows provided in the window frame.

Abstract: Image processing systems can include one or more cameras configured to obtain image data, one or more memory devices configured to store a classification model that classifies image features within the image data as including or not including detected objects, and a field programmable gate array (FPGA) device coupled to the one or more cameras. The FPGA device is configured to implement one or more image processing pipelines for image transformation and object detection. The one or more image processing pipelines can generate a multi-scale image pyramid of multiple image samples having different scaling factors, identify and aggregate features within one or more of the multiple image samples having different scaling factors, access the classification model, provide the features as input to the classification model, and receive an output indicative of objects detected within the image data.

Abstract: A sensor interface for an autonomous vehicle. The sensor interface generates a plurality of sensor pulses that are each offset in phase relative to a local clock signal by a respective amount. The sensor interface receives sensor data from a sensor apparatus and formats the sensor data based at least in part on the plurality of sensor pulses to enable the sensor data to be used for navigating the autonomous vehicle. For example, the sensor interface may add a timestamp to the sensor data indicating a timing of the sensor data in relation to the local clock signal.

Abstract: A sensor synchronization system for a sensor apparatus. The system synchronizes a local clock signal with an external timing signal. For example, the external timing signal may correspond to a pulse per second (PPS) signal received from a global positioning system (GPS) receiver. The system further generates a plurality of sensor pulses that are each offset in phase relative to the local clock signal by a respective amount. The system then receives sensor data from the sensor apparatus, and determines a timing of the sensor data in relation to the local clock signal based at least in part on the plurality of sensor pulses.

Abstract: A medical electrode system and method comprises four measuring electrode elements and optional reference electrodes each presenting a skin contactable conducting electrode surface, the four elements adapted to be mounted in use on the skin surface of a selected part of the human or animal body so as to be disposed in a generally orthogonal arrangement with the outputs therefrom being arranged and processed so as to connect the electrode elements either as opposing differential pairs or as potentials with respect to the reference electrode(s) where present

Abstract: A heart rate monitor apparatus and method are described. The apparatus consists of multiple recording electrodes each incorporated into a contact surface for application to an external body surface of a human or animal subject and a data acquisition and processing system to process the data by way at least of the steps of producing a frequency and/or signal intensity based data characterisation and inferring and outputting therefrom a result representative of the heart beat rate of the subject. In particular the data processing method involves deriving the result by identifying a peak in the frequency and/or by signal intensity based data characterisation for example by producing a power density spectrum, identifying the peak power frequency and, outputting the result as a result representative of the heart beat rate of the subject.
