Portable transaction terminal apparatus adapted for use in eating and drinking establishments. A terminal housing has a generally rectangular shape and a size slightly larger in length and width to corresponding dimensions of a restaurant guest check. A folio-type cover is mounted to a left side portion of the terminal housing by a hinge arrangement and thereby adapted to swing between open and closed cover positions, the cover corresponding in length and width to the terminal housing so as to completely cover a top face of the terminal housing in the closed cover position and to lie flat against a surface in the open cover position. A data entry keypad and an alphanumeric display are carried on the top face of the terminal housing. A card reader module is mounted in the terminal housing for accepting and reading a transaction data card selected for use by a guest of the establishment for payment of the amount of the guest check. A microcomputer system is carried within the terminal housing and being pre-programmed with operating system and application software for management of data entry, message display, card reading and transaction message formatting and storing functions associated with a preselected data entry sequence and data message format. The microcomputer system communicates a transaction data message to an external transaction terminal system for completion of transaction processing steps. A docking station is provided for communication with a transaction terminal. Recharging stations with intelligent charge controllers are provided for recharging the batteries of the portable transaction terminal.

A connecting device for fuel injection systems is used for connecting a fuel injection valve to a fuel-carrying component. A wire-shaped connecting element is provided in this context, which is fastened, on the one hand, to the fuel-carrying component and, on the other hand, to the fuel injection valve. The wire-shaped connecting element is embodied closed in an annular manner, and, on the one hand, is guided about a shoulder of the fuel-carrying component and, on the other hand, about a shoulder of the fuel injection valve. A fuel injection system having such a connecting device is also provided.
摘要:
A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.

A system and method for searching real estate uses non-traditional techniques. A selection of suggestive imagery may be rated by a user in order to indicate that user's subjective tastes. The suggestive images may relate to particular keywords which also may be related to real estate listings. This way, properties which appeal to a user's tastes may be identified and sorted accordingly.
摘要:
An internal combustion engine control apparatus, which is for a vehicle which runs on power from an electric motor, derives a required power of the electric motor, derives a power that the electric motor can output by electric power supplied from the battery, derives an optimum power in the generator based on the required power and an attainable power, determines an operation mode of the internal combustion engine based on a magnitude of the optimum generator power, derives an offset value for correcting an operation point of the internal combustion engine when operated in a constant point operation mode, derives, based on the optimum generator power, a target operation point for the internal combustion engine operated in the constant point operation mode, and controls the internal combustion engine to operate at an operation point which is obtained by correcting the target operation point by the offset value.
摘要:
