An apparatus and method for measuring indicator concentration time curves optically from a living organism using a single wavelength, by comparing the optical density before and after injection of the indicator and by selectively utilizing the values of the concentration of blood hemoglobin, blood oxygen saturation, or the mean optical pathlength in the computation. Whereby, physiological parameters such as cardiac output, blood flow and blood volume can be calculated by analyzing the indicator concentration time curves.

A transmission apparatus comprising a wave actuator having a wave-actuating disk mounted on an eccentric body through a rolling bearing; an oscillatory roller gear having Zh number of oscillatory rollers assembled in Zh radial slots of an oscillatory roller carrier, and a stationary gear with Zg number of inner teeth, where Zg=Zh. +-. 1. The wave actuator pushes the oscillatory rollers to move radially. The oscillatory rollers roll along the inner surface of the stationary gear, driving the oscillatory roller carrier to rotate, thereby transmitting movement and power. Any one of the three components: the wave actuator, the oscillatory roller gear, and the stationary gear, can be chosen as a fixed component; the other two then form a speed-reducing or a speed-increasing transmission. When none of the components are fixed, they form a two-in/one-out differential transmission.

The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.

The present utility model relates to a device for improving gas detection in a photoionization detector. A gas detector is provided. The device reduces interference of photoelectric noise on the reading of the gas detector for target gases such as volatile organic compounds.
