    • An intelligent medical vigilance system that observes and analyzes, and, only in the event of a clinically significant negative condition, notifies and reports the event to the care staff utilizing the hospital's existing nurse call system. The device includes a bedside unit connected to a pad or coverlet with a sensor array (placed under the patient) and also to an existing hospital nurse call system via an interface. Within the physical bedside unit are a signal processor and an alarm processor that measure data and evaluate whether a clinically significant event is occurring. The bedside unit is a wall-mounted unit with a display that becomes active when an alarm condition is enabled. The sensing pad or coverlet is a thin, piezoelectric film, or other similar sensing technology, with an array of sensors sheathed in soft padding and is not directly in contact with the skin of the patient. The nurse call feature is made up of hardware, software and cabling to connect to the nurse call system already installed in the hospital or care facility. The monitoring system can also be installed in vehicles to monitor operator physiological conditions. Vigilance alarms are suspended if a patient is detected out of bed. An unable-to-measure alert is provided if the system is unable to reliably monitor. Bed exit alarms can be placed into a pause mode for supervised bed exit of patients on bed restriction. An alert message is generated and maintained on the display screen to inform a responding caregiver of the time and reason for any alarm.
    • 一个智能的医疗警戒系统,用于观察和分析,只有在出现临床重大的负面情况的情况下,才能使用医院现有的护士呼叫系统向护理人员通报并报告事件。 该装置包括连接到具有传感器阵列(放置在患者下方)的垫或盖板的床边单元以及经由界面到现有医院护士呼叫系统的床边单元。 物理床边单元中的信号处理器和报警处理器可以测量数据并评估临床重要事件是否发生。 床头单元是带有显示屏的壁挂式单元,当启用报警条件时,显示屏将起作用。 传感垫或盖板是薄的压电薄膜或其它类似的传感技术,其中一组传感器套在软垫中,并且不直接与患者的皮肤接触。 护士电话功能由硬件,软件和电缆组成,连接到已经安装在医院或护理机构中的护士呼叫系统。 监控系统也可以安装在车辆中,以监控操作员的生理状态。 如果患者被检测出床,警觉警报将被暂停。 如果系统无法可靠地监控,则提供无法测量的警报。 卧床出口报警器可以进入暂停模式,用于床限制患者的监督床出口。 在显示屏幕上生成并维护警报信息,以通知响应的看护者任何警报的时间和原因。

    • Passive Physiological monitoring apparatus and method have a sensor for sensing physiological phenomenon. A converter converts sensed data into electrical signals and a computer receives and computes the signals, and outputs computed data for real-time interactive display. The sensor is a piezoelectric film of polyvinylidene fluoride. A band-pass filter filters out noise and isolates the signals to reflect data from the body. A pre-amplifier amplifies signals. Signals detected include mechanical, thermal and acoustic signatures reflecting cardiac output, cardiac function, internal bleeding, respiratory, pulse, apnea, and temperature. A pad may incorporate the PVDF film and may be fluid-filled. The film converts mechanical energy into analog voltage signals. Analog signals are fed through the band-pass filter and the amplifier. A converter converts the analog signals to digital signals. A Fourier transform routine is used to transform into the frequency domain. A microcomputer is used for recording, analyzing and displaying data for on-line assessment and for providing realtime response. A radio-frequency filter may be connected to a cable and the film for transferring signals from the film through the cable. The sensor may be an array provided in a MEDEVAC litter or other device for measuring acoustic and hydraulic signals from the body of a patient for field monitoring, hospital monitoring, transport monitoring, home, remote monitoring.

    • A lysimeter has an elongated, relatively narrow sample pipe with flanges at upper and lower ends. A lysimeter assembly is connected to the lower end of the sample pipe by connecting an upper end of a central tube in the assembly to a lower end of the sample pipe. A circular lysimeter pan extends around the central tube. Vertical slits in the central tube provide a screen to permit water flow into the central tube from the pan but to prevent granular materials from the filter pack. Vertical webs in the pan rigidify the pan, and radial supporting webs and a ring beneath the pan support the pan. A relatively large diameter collection chamber has a spheroidal lower end and an upper end which receives the ring for centering the lysimeter pan at the upper end of the collection chamber. An outward and upward sloping flange at an upper end of the collection chamber with an elastic seal supports the lower conical wall of the lysimeter pan. A wick in the pan extends through slits in the central tube to wick water from the pan into the central tube and to flow water down along the inner wall of the central tube. The bottom of the central tube is open and is sloped, and an upward opening inner groove is formed around the lower end of the central tube. A drain tube is connected to a lower portion of the groove. A sampler is raised and lowered and positioned by a rod or chain extending through the sample pipe and central tube, so that a funnel at the upper end of a flask is aligned with the drain tube. Drain openings are provided in the canister bottom.

    • A moisture control device and method has a heat generating source in electrical devices that is powered to operate independent of the electrical device for reducing, minimizing or preventing condensation, nucleation and degradations on electronic parts and circuit boards of the electrical device. A power supply is connected to the heat generating source and a switch connected to the power supply. The switch may be manually operable or automatic and is used for controlling operation of the heat generating source. A sensor senses on/off status of the electrical device and automatically operates the switch in response to the sensing. Power is supplied to the heat generating source when the electrical device powers down and disconnected when the electrical device powers on.
