  • Publication number: 20060132444
    Abstract: A glove input device with two gloves and an encoder is described. Each glove has several finger parts for the insertion of fingers. The front and back of the finger part have several contact points. The contact points on the thumb are defined as the first set of contact points, those of the rest finger parts the second set of contact points. When any of the first set of contact points is in touch with any of the second set of contact points, a current loop is formed to generate a current signal. The encoder receives the current signal and outputs a corresponding character code signal of the contact points in touch.

  • Patent number: 6642725
    Abstract: A method for testing for radiation on a synchronized dynamic random access memory (SDRAM), wherein an irradiation controller irradiates the SDRAM. The status of the SDRAM after a radiation test are calculated. The radiation tests comprise SEU, micro latch-up, SEL and get rapture tests. From the radiation test, we can understand the condition of the SDRAM before and after the radiation test.

  • Publication number: 20020140431
    Abstract: A radiation test system that couples with a radiation test field and a radiation controller. The radiation controller records the flow of radiation particles and the test results obtained from a test component. The radiation controller also controls a radiation particle accelerator so that the test component is irradiated with a cyclically varying radiation beam. The radiation test system further includes a daughter board, a motherboard, a power source, a near-end monitor and a far-end monitor. The near-end monitor is responsible for initiating a test program to test the test program, monitoring the test status and recording the test data. The far-end monitor remotely controls the near-end monitor to initiate an irradiation testing of the test component. The far-end monitor also receives test data submitted by the near-end monitor so that test results may be further analyzed.
