Abstract: Systems, methods, and computer program products for access-related safety determinations are provided. An example method includes receiving first image data of a field of view of a first imaging device that includes an access location and determining an access condition of the access location based upon the first image data. In response to an attempt to access the access location by a first user, the method includes receiving second image data of a field of view of a second imaging device that includes the first user upon which to perform a safety determination. The method further includes generating a safety parameter for the first user that is indicative of a presence and a positioning of a safety device of the first user, comparing the safety parameter with a validation threshold, and generating an alert signal in an instance in which the safety parameter fails to satisfy the validation threshold.

Abstract: A method for alerting a user on an electronic device is described. The method includes identifying a signal at an ultrasound transmission frequency received at a first electronic device from a second electronic device. Further, the method includes receiving timing information corresponding to an exchange of an ultrasound transmission between the first electronic device and the second electronic device. Furthermore, a first distance value between the first electronic device and the second electronic device is computed by performing a time of flight estimation using the timing information. Furthermore, the first distance value is refined by using an output of a machine learning model to determine a second distance value. Furthermore, the method includes generating an alert based on the comparison of the second distance value with a predefined threshold distance value. In some examples, the alert can be indicative of a violation of a physical distancing norm in an environment.

Abstract: A battery charger is disclosed for use with various batteries, such as automotive- and marine-type batteries. In accordance with an aspect of the invention, the charging current is alternated between non-zero DC charging current levels. By alternating the charging current between non-zero DC charging levels, the battery can be charged to a higher capacity (i.e., ampere hours) faster, thus reducing the charging time and at the same time allow the rating of the battery charger to be increased. In accordance with another important aspect of the invention, the technique for alternating the charging current can be implemented in both linear- and switched-mode battery chargers.

Abstract: A GUI is described, which is operable on mobile device touchscreens. The GUI has a programmable scan zone, placed over a first portion of the touchscreen, operable on the touchscreen for receiving a first input at an instance in time, and invoking one or more functions of the mobile device, based on a user programmed context, programmably in response to that received input. The GUI also comprises a configurable virtual trigger icon placed over a second portion of the touchscreen with an area smaller than the first. The icon is operable for receiving a second input and, based on a user configured selection or context, triggering responsively a corresponding action related to the one or more functions of the mobile device. The mobile device functions include applications, tools, macros or menus related to collecting or accessing visible graphic and other data (e.g., barcodes, images, RFID/NFC tags).

Abstract: A parking access control system and a method of its operation in association with a parking facility. A customer operates a call box to initiate a communications session with an attendant control device operated by an attendant. In particular, the customer requests the attendant to control an exit gate so as to enable the customer to exit the parking facility with a vehicle. In response, the attendant may input into the attendant control device one of several available predetermined override conditions, which will be logged as an override transaction entry in a database in memory. After the override condition is entered, then the exit gate will operate so as to enable the customer to exit the parking facility. The override transaction entry further may also include an identification of the attendant.
