Publication number: 20180092556Abstract: In an embodiment, a sensor module 10 includes a piezoelectric element 30 placed on the principal face of a board 20, which piezoelectric element is surrounded by a vibration ring 40 and installed in an appropriate position on a person's arm, neck, etc., using a medical fixing tape, etc., with the vibration ring 40 contacting the person's skin. When a pulse wave is transmitted to the vibration ring 40 from the skin, the board 20 also vibrates and this vibration is transmitted to the piezoelectric element 30. Then, the piezoelectric element 30 is displaced and the pulse wave vibration is converted to an electrical signal. The resulting electrical signal is amplified by an amplifier on the board 20 and input to the vibration analysis device 100, where prescribed calculations are run to perform waveform analysis. The vascular state, etc., can be known from pulse waveforms.Type: ApplicationFiled: April 9, 2016Publication date: April 5, 2018Inventors: Takashi ISHIGURO, Keiichi KOBAYASHI, Yutaka AOKI

Jitter buffering control for controlling storage locations of a jitter buffer, and a method therefor
Patent number: 8379675Abstract: A jitter buffer control apparatus has a buffer for storing data included in an input packet transmitted from a telecommunications network, and a jitter buffer controller for controlling the buffer to store the input data into the buffer and take out the stored data from the buffer on the basis of a sequence number included in the input packet in a processing period. When under-running occurs in the buffer, the jitter buffer controller stores input data into the buffer with a storage location skipped which corresponds to the processing period associated with packet loss due to the under-running.Type: GrantFiled: March 10, 2010Date of Patent: February 19, 2013Assignee: Oki Electric Industry Co., Ltd.Inventor: Takashi Ishiguro -
