Abstract: The embodiments described herein provide systems and methods that can improve performance in scanning laser devices. Specifically, the systems and methods emit emission control pulse sets that are used to detect when objects (e.g., persons) are within a relatively close safety range. Then, higher energy long-range pulse sets are conditionally emitted only when objects were not detected within the safety range with the emission control pulse sets. These emission control pulse sets are emitted variable timing and/or variable energy that is determined at least in part on whether previous emission control pulse sets detected an object with the safety range. The use of emission control pulse sets with variable timing and/or variable energy can provide for improved reliability of object detection in a safety range, while still meeting the energy limits needed for eye safety.

Abstract: A motorised kart (10) has a chassis (12), a front wheel axle (14), an engine (16) mounted to the chassis and a transmission to transmit drive from the engine to the front wheel axle. The transmission includes a differential unit (20).

Abstract: Methods and apparatus, including computer program products, are provided for ballot generation. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: The subject matter disclosed herein provides methods for authenticating a voter's identity using an electronic polling device. The method may search a plurality of voter profiles for a desired voter profile associated with a voter. The searching may be based on at least the voter's name or an associated voter ID. The method may display the desired voter profile which may include at least an image of the voter and an image of the voter's signature. The method may receive confirmation information from the voter. The method may compare the received confirmation information and a physical likeness of the voter with the desired voter profile to enable an authentication of the voter based on the comparing. The searching, displaying, receiving, comparing, and authenticating may be performed by at least one processor in an electronic polling device. Related apparatus, systems, techniques, and articles are also described.
