摘要:
A point of sale (POS) system includes primary and auxiliary printers powered by a shared power supply. A POS terminal includes the shared power supply, a user interface, and a host including a printer driver for dynamically generating primary print commands. A printer connection card connected to the POS terminal includes a Universal Serial Bus (USB) hub in communication with the host and having at least one USB connector powered by the shared power supply. The primary printer is connected to the USB hub for receiving power and the primary print commands through the USB hub from the POS terminal. An auxiliary printer has a power-only connection to the printer connection card, receiving independently generated auxiliary print commands from a separate host computer. A controller includes control logic for selectively blocking the primary print commands to the primary printer in response to the signal drawn by the auxiliary printer exceeding a threshold.

Graphical retail item identification including receiving, from a digital camera, an image of a retail item to be identified; decoding, by an image decoding module, the image into one or more image processing tasks; assigning, by a task assignment engine, the one or more image processing tasks to one or more of the POS terminals, the one or more POS terminals characterized as image processing terminals; executing the image processing tasks by the image processing terminals, including reporting results of the image processing tasks to an item identification engine; and identifying, by the item identification engine upon completion of the image processing tasks by the image processing terminals, the retail item.
摘要:
Method, system and apparatus enabling a computing system to automatically identify the capabilities of a power supply coupled to the computing system. The power supply includes a controller that sends an identification code to a computing system prior to sending a power good signal to the computing system. The identification code and the power good signal are preferably sent over a single conductor, such as a power supply connector pin. The computing system receives the identification code for cross-referencing against a list of power supply identification codes and associated capabilities. Optionally, instructions from the computer system to an output device may be controlled as a function of the identified power supply capabilities.

Apparatus for lifting and towing vehicles includes a boom assembly which can be folded and unfolded by use of hydraulics. Drumstick shaped members are connected at the end of the boom assembly and can be moved to engage and hold tires or wheels of towed vehicles in cooperation with a bar member also attached at the end of the boom assembly.
摘要:
Multi-mode computing systems for point of sale transactions are disclosed. According to an aspect, a computing system includes a first housing and a processing device disposed in the first housing. A user interface and a first input/output interface is integrated with the first housing and in communication with the processing device. The first input/output interface is configured to receive power for delivery to the processing device. A second housing is configured to carry the first housing. An attachment mechanism is configured to selectively attach together the first housing and the second housing for carry of the first housing. A second input/output interface is configured to be communicatively coupled to the first input/output interface when the first housing and the second housing are attached. A power source is connected to the second input/output interface for delivery of power to the processing device via the first input/output interface.
