A wireless communication device performs a communication with a communication device wirelessly. The wireless communication device comprises a communication information acquisition unit, a selection unit, and a communication unit. The communication information acquisition unit acquires a communication information from the communication device using a short distance wireless communication, the communication information indicating a plurality of communication paths available to the communication device and other than the short distance wireless communication. The selection unit selects one of a plurality of communication paths other than the short distance wireless communication based on the communication information. The communication unit performs a communication with the communication device in the selected one of the plurality of communication paths. The selection unit selects one communication path available to both the wireless communication device and the communication device according to a predetermined information indicative of priority criteria for selecting a communication path.

Wireless communication device, wireless communication method, wireless communication device control program, and wireless communication system

To perform a communication by selecting an appropriate communication path when there are a plurality of communication paths between two wireless communication devices. A wireless communication device is provided with an opposite side device communication information acquisition means acquiring opposite side device communication information, which indicates a communication path of a wireless communication in the communication device that is to be a communication partner, from the communication device in a short distance wireless communication; a communication information acquisition means acquiring communication information, which indicates a communication path of a wireless communication in own device; a selection means selecting a communication path used for a communication with the communication device among a plurality of communication paths based on the opposite side device communication information and the communication information; and a communication means performing a communication with the communication device in the selected communication path.

To make it possible for a user to easily send data, the invention is provided with: a candidate addressee display unit for receiving information relating to a candidate addressee from a data transfer server and displaying an addressee selection screen so that the candidate addressee can be selected; an addressee setting unit for notifying the data transfer server of a selection result from when the candidate addressee has been selected, and thereby setting the addressee; a data acquisition unit for acquiring data intended to be sent; and a transmission control unit for sending the data intended to be sent to the data transfer server and thereby causing the data intended to be sent to be transferred from the data transfer server to the addressee.

A tube valveof the present invention includes a tubedefining a flow path therein through which a fluid flows, the tubebeing arranged so that a part of the tubeforms at least one curved portion; and an opening/closing mechanism which closes the flow path by folding the tubeat the at least one curved portion and opens the flow path by releasing the fold of the tubeThe curved portion has a bendable part (bending portion)where the tubecan be bent, and the tubeis folded by bending the bendable partFurther, a tube valve apparatus may include the tube valveof the present invention. Furthermore, a head cleaning apparatus for cleaning a head of a printer of the present invention may has one or more tube valveor tube valve apparatus.

An air supply device is provided on a rotating body having an air filling portion into which air is filled. The air supply device has a device body provided with a cylinder, and a piston mounted movably in the cylinder, the device body being joined at the middle of a valve so that a through-hole is communicated to a flow passage of the valve. A direction, in which the piston is moved, corresponds substantially to a radial direction of a tire unit (wheel), and the piston can be moved by a centrifugal force, which is generated by rotation of the tire unit. A latch for latching the piston is formed below the piston in the cylinder, in which a coil spring is mounted. Also, the device body is provided with an adjusting screw, check valves, and an air filter.

An airship system according to the invention has an airship (), a base station (), and at least three measurement points. The airship () emits ultrasonic waves upon receiving an instruction from the base station (). Measurement point units (S-S) receive the ultrasonic waves, and thereby measure distances from the airship () to the respective measurement points. An MPU that is incorporated in the base station () calculates a position of the airship (). The base station () controls a route of the airship () based on the calculated position by sending a flight instruction to the airship (). In this manner, an airship system can be provided that makes it unnecessary for an operator to pilot the airship and that can reduce the load weight and the power consumption of the airship.

A cabinet is formed on the top face with an entry opening for rolled paper, and a storage section for accommodating the rolled paper. A cover is provided for opening/closing the entry opening, and the upper front of the cover is provided as a slipsheet entry face for inserting a slipsheet. The slipsheet entry face is formed in one side margin with a slipsheet guide along the insertion direction of the slipsheet. A paper discharge slot of the rolled paper is formed by a gap between a buff portion of the cabinet and the tip of the cover, when the cover is closed. The paper discharge slot is at a position lower than that of the slipsheet entry face. A slipsheet print section is placed on the upper rear portion of the cover.

Printer with cutter blades for printing on rolled paper and slipsheet

An emulator that emulates the operation of a target machine on an execution machine is disclosed. The execution module prepared for each function of the target machine is called via a dispatcher from a kernel. A calling address is registered in a dispatcher table by the execution module when each execution module is loaded. Inputs from a keyboard causes a hardware interrupt resulting in the calling of a keyboard emulator. After a converted key code is stored in a buffer, an interrupt controller emulator is called by intermodule communication. The interrupt controller emulator requests a virtual interrupt for the kernel. The keyboard emulator is called again and the key code stored in the buffer is transmitted to the application program.

Computer peripheral function emulator

What is disclosed is an emulator that emulates on an execution machine the operation of a target machine. The emulator emulates routines that are called via a jump table such as the BIOS. Control is transferred to an emulation module not by directly trapping the procedure to call the BIOS but by placing a privileged instruction (a halt instruction, for example) in the area called and by causing a trap through the execution of the privileged instruction. An identifier is placed after the halt instruction and a needed BIOS emulation module is called by a dispatcher using this identifier. Therefore, normal operation can be obtained even if there is a resident program which rewrites the jump table.
