An optical image reader is provided. The image reader includes, for example, a targeting system for an imager, which includes a light device having a plurality of light emitting diodes (LEDs), each for emitting light, and a device for shaping a single targeting light based on the outputs of the plurality of LEDs. The image reader includes, for example, an image system for capturing image of an indicia on an object, which includes a targeting light source for providing a targeting light to the indicia on the object; and an optical system for focusing reflection from the object, having a liquid focus lens element having a variable focus, and a controller for controlling the focus of the focus lens. The image reader includes, for example, a system for capturing an image of an indicia on an object, which includes an image sensor for sensing reflection from the object, and an ambient light sensor for sensing the reflection from the object prior to the sensing by the image sensor to calculate a first estimate for exposure of the image sensor.

A system and method are described for locking a touch sensitive screen input component of a device. The system and method receives input from an input component, adds the received input to a input sequence, and checks the input sequence against a key sequence. If the input sequence matches the key sequence, the system and method toggle the locked state of device input components.

A multi-field antenna (300) is configured to be able to receive a signal over one of a plurality of different fields in response to a switch. The multi-field antenna (300) comprises a mobile computer interface (316), first (302) and second (304) magnetic loops, and a first metallic element (308). The mobile computer interface (316) interfaces the multi-field antenna (300) with a mobile computer for receiving and processing the signal. The first magnetic loop (302) is tuned by a first tuner (312) to provide a first field for reading data. The second magnetic loop (304) is tuned by a second tuner (314) to provide a second field for reading data. The second field is narrower than the first field. The first metallic element (308) covers at least a portion of the second magnetic loop (304) and comprises a slot (320) extending along its length from one end of the first metallic element (308) to a point proximal an opposite end of the first metallic element (308).
摘要:
A battery module mount for securing a battery module to a housing of a handheld device, including one or more latch elements attached to the housing and movable between a free position and an unlatched position, with a tab portion, and one or more elongate resilient elements biasing each latch element to the free position. Each latch element is positionable in a latched positions. The mount also includes one or more mating means attached to the battery module with an abutment with which the tab portion is engageable when the latch element is in the latched position, to hold the abutment in a retainable position, thereby securing the battery module to the housing. The tab portion is disengaged from the abutment when the latch element is in the unlatched position, to permit removal of the battery module from the housing
摘要:
A system and method are described for displaying battery information on a display of a portable computer. After powering on the portable computer, battery information of a battery of the portable computer is retrieved. The retrieved battery information is displayed on the display of the portable computer and the operating system (OS) loaded into an executable memory of the portable computer is executed after the display of the battery information.
