    • A bed exit and patient detection system especially adapted for use in the general medical or surgical floor area of a hospital or other healthcare facility as part of a vital signs monitoring and remote warning system includes a plurality of pressure sensors disposed in the patient's bed in a series of rectangular strips or zones that run laterally across the bed in the area of the patient's mid-back, hips and mid-legs, respectively. Each zone contains a plurality of sensors, arranged symmetrically about the centerline of the bed, with the corresponding sensors on opposite sides of the centerline in each zone being connected in parallel. The sensors are connected to a processor with multiple input channels that continuously monitors the sensor states to determine, from the pattern of sensor states observed, whether the patient is in bed, out of bed or is actively attempting to ext the bed at the sides or foot of the bed. At least three different sets of bed exit logic rules are available for user selection to configure the system for high, medium or low sensitivity, or bed exit privileges, for any particular patient. In some embodiments, the system also is capable of detecting when a patient is attempting to assume certain prohibited in-bed positions, such as sitting positions or slumping positions. An alarm in the form of a pre-recorded voice announcement or an alarm over a pre-existing nurse call system is provided when the sensor states are indicative of an out-of-bed or an exiting bed condition, or other prohibited in-bed positions, for a predetermined minimum period of time.
    • 特别适用于医院或其他保健设施的一般医疗或手术地板区域的床出口和患者检测系统,作为生命体征监测和远程警告系统的一部分,包括设置在患者床上的多个压力传感器 分别在患者的中后背,臀部和中腿的区域横向穿过床的一系列矩形条带或区域。 每个区域包含多个传感器,围绕床的中心线对称布置,每个区域中心线对面的对应传感器并联连接。 传感器连接到具有多个输入通道的处理器,该输入通道连续地监测传感器状态,从所观察到的传感器状态的图案中确定患者是否在床上,脱离床或正在积极地尝试在侧面分开床,或者 床的脚。 对于任何特定的患者,至少有三组不同的床退出逻辑规则可用于用户选择以配置系统的高,中或低灵敏度或床退出特权。 在一些实施例中,系统还能够检测患者何时试图假定某些禁止的床位置,例如坐姿或塌落位置。 当传感器状态指示出床或退出床状况或其他禁止的床上状况时,提供以预先录制的语音通知或预先存在的护士呼叫系统的警报的形式的警报 位置,预定的最小时间段。

    • In general, the present invention is directed to systems and methods for finding the position and shape of an animal using video. The invention includes a system with a video camera coupled to a computer in which the computer is configured to automatically provide animal segmentation and identification, animal motion tracking (for moving animals), animal-posture classification, and behavior identification. In a preferred embodiment, the present invention may use background subtraction for animal identification and tracking, and a combination of decision tree classification and rule-based classification for posture and behavior identification. Thus, the present invention is capable of automatically monitoring a video image to identify, track and classify the actions of various animals and the animal's movements within the image. The image may be provided in real time or from storage. The invention is particularly useful for monitoring and classifying animal behavior for testing drugs and genetic mutations, but may be used in any of a number of other surveillance applications.
    • 通常,本发明涉及使用视频来找到动物的位置和形状的系统和方法。 本发明包括具有耦合到计算机的摄像机的系统,其中计算机被配置为自动提供动物分割和识别,动物运动跟踪(用于移动的动物),动物姿势分类和行为识别。 在优选实施例中,本发明可以使用用于动物识别和跟踪的背景减除,以及用于姿势和行为识别的决策树分类和基于规则的分类的组合。 因此,本发明能够自动监视视频图像以识别,跟踪和分类各种动物的动作和图像内动物的动作。 图像可以实时地或从存储提供。 本发明特别可用于监测和分类用于测试药物和遗传突变的动物行为,但可用于许多其他监视应用中的任何一种。
