An authentication method and apparatus at a wireless LAN (local area network) system based on the IEEE 802.11, in which many STAs (terminal stations) are connected to APs (access points), and which can keep the security in authentication, is provided. At the authentication method, an authentication request from one of the STAs composed of a data terminal and a wireless LAN card is transmitted to one of the APs. The AP transmits a MAC (media access control) address of the STA to an authentication server by converting the authentication request to a protocol adaptable to the authentication server. The authentication server checks the MAC address and transmits a challenge message to the AP 2. The AP 2 executes encryption authentication with the STA based on a WEP (wired equivalent privacy) algorithm stipulated in the IEEE 802.11.

Surgical instruments are provided for performing laparoscopic or similar minimally invasive operations, including two clamping parts, which can move towards one another and which have clamping surfaces for gripping tissue when they are closed.

In such an instrument the cutting direction extends at an acute angle to the clamping surfaces when they are closed.

A carwash includes a single thru-beam or retroreflective photoelectric sensor that can determine the position of a vehicle's left side, right side, front end and back end. To accomplish this, the sensor is coupled to a spray arch that travels around the vehicle while spray washing the vehicle's exterior. In some embodiments, the sensor responds to a beam projected from an emitter that also travels with the spray arch, whereby the emitter, the sensor and the spray arch move in unison. The beam is preferably projected at an acute angle to a horizontal plane so that the sensor can detect the presence of the vehicle without the spray arch having to get too close. To avoid over twisting the sensor's electrical cable, the arch alternately rotates CW and CCW to limit cumulative rotation in any one direction. In some cases, the single sensor responds to beams from multiple emitters.
