Abstract: A device for communication with a terminal. The device comprises: a communication unit for communicating with the terminal; a biometric unit comprising a biometric sensor for sensing biometric data; contacts for connecting the device to the terminal; a first physical interface between the biometric unit and the contacts configured to enable contact communication between the biometric unit and the terminal; and a second physical interface between the communication unit and the biometric unit configured to enable contact communication between the communication unit and the biometric unit. The device is configured such that all contact communications between the terminal and the communication unit are routed through the biometric unit via the first and second physical interfaces.

Abstract: A method includes: obtaining a pose of a mobile computing device associated with a worker in a facility; detecting a trigger event to initiate presentation, at the mobile computing device, of visual guidance corresponding to one of a plurality of mobile robots in the facility; in response to detecting the trigger event, selecting one of the mobile robots; determining, based on the pose of the mobile computing device and a map of the facility, whether the selected one of the mobile robots is visually obstructed from the pose of the mobile computing device; and when the selected one of the mobile robots is visually obstructed, providing visual guidance via the mobile computing device, the visual guidance indicating a current location of the selected mobile robot behind an obstruction.

Abstract: A method in a computing device includes: storing an initial map representing objects within a facility; receiving sensor data from a mobile robot deployed in the facility, the sensor data representing a portion of the facility within a field of view of the mobile robot; determining, based on the received sensor data, whether a map update criterion is satisfied; in response to determining that the map update criterion is satisfied, generating a map update representing updated objects within the facility; applying the map update to the initial map to generate an updated map; and storing the updated map.

Abstract: A method includes: maintaining data handling settings at a mobile robot; generating operational data at the mobile robot, the operational data defining a current state of the mobile robot; storing the operational data in a memory of the mobile robot; selecting, based on the data handling settings, a portion of the operational data; transmitting the selected portion of the operational data; in response to a determination that the operational data meets a condition, obtaining updated data handling settings; and selecting a subsequent portion of the operational data for transmission according to the updated data handling settings.

Abstract: A compact reflector telescope has a spherical primary reflector and a secondary reflector with a negative lens interposed there between in axial alignment therewith. Light reflected from the primary reflector is passed through the negative lens and is diverted by the secondary reflector to a positive lens at the side of the telescope tube. The positive lens focuses the light rays onto an eye piece or ocular or onto a photographic emulsion or electronic detector. The telescope reduces or substantially eliminates spherical aberration and can be configured to have a focal ratio significantly greater than the focal ratio of the primary reflector. The telescope produces a flat field of view and an image which is substantially diffraction limited.
