Abstract: PROBLEM TO BE SOLVED: To provide a deformation luminous intensity measuring instrument that can measure deformation luminous intensities in three-dimensional directions, by fixing either the incident angles or light-receiving angles to a certain fixed angles. SOLUTION: A light-receiving unit 37 is rotated about a normal line (vertical axis) to the surface of a sample 24 by means of a pulse motor 31 and, in addition, is rotated in the forward and backward directions about around a prescribed horizontal axis in Fig. 1 by means of a pulse motor 34. A light source unit 29 is rotated in the forward and backward directions about the prescribed horizontal axis in Fig. 1 by means of a pulse motor 26. Rotation of the light source unit 29 about the vertical axis is substituted, by the rotation of the sample 24 about the normal line to the surface of the sample 24 by means of a pulse motor 22.  Since the light source unit 29 and the light-receiving unit 37 are thus rotated and controlled separately, and as a result, this measuring instrument can measure the deformation luminous intensity by fixing either the incident angle or light-receiving angle to the certain fixed angle.

Title: Unified channel access for supporting quality of service in a local area network
Inventor: HO JIN-MENG
IPC: H04L12/28
Filed: 2001-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a hybrid of contention-free communications and contention communications for a shared communications medium. SOLUTION: Contention communications often require a station to wait an inordinate amount of time before the station is able to transmit its data successfully. In many applications, an extended delay is not acceptable. Contention-free communications in a contention period allows a hybrid coordinator (HC) to schedule contention-free access to a communications medium so that extended delays may be eliminated, and to coordinate contention access to the medium so that better throughput and delay performance is achieved. A method for creating contention-free communications within a contention communications period is presented, along with adaptive algorithms for contention access during the same contention period.  In one embodiment of this invention, the method provides contention-free transmission during a contention period in a shared communications medium comprising capturing the shared communications medium (660), permitting a recipient to transmit, and recapturing the shared communications medium after the recipient transmits.
