  • Patent number: 11130454
    Abstract: A module driver or a master obtains the load IDs of the respective first loads connected to the downstream side of the module driver, recognizes the classification of areas, such as door, roof and floor areas, or a module according to the obtained load IDs, and allocates an appropriate driver ID to the module driver in each area. Each first load has a load ID. The load IDs are allocated to the respective second loads on the downstream side of the module driver on the basis of the allocated driver ID. The area or the module is recognized on the basis of the combination of the load IDs of the plurality of first loads, whereby malfunctions caused by erroneous assembling of the first loads are suppressed.

  • Patent number: 8514093
    Abstract: A sheet switch (142) has a bottom layer (144) and a top layer (160). First and second conductors (148, 162) located on the bottom layer (144) form two separate conductive paths, with a voltage potential applied to the conductors (148, 162). The top layer (160) includes a ground conductor (172). Spacers (178) are positioned between the top and bottom layers (160, 144). When forces are externally applied, the spacers (178) collapse and the ground conductor (172) contacts the first and second conductors (148, 162), and establishes a conductive path therebetween.

  • Patent number: 8466801
    Abstract: The patient monitoring system comprises at least one load cell element (12) mounted in relation to a support surface, the load cell element (12) determining movement of a person on a support surface. The movement is determined based on a reference (31) measured using the load cell element (12) when the person is positioned on the support surface in a reference position and the subsequent load changes determined using the load cell element in relation to the reference. If the load change exceeds a pre-defined threshold, an alarm (18) is activated. The user is able to set the threshold value of the alarm system according to the physical condition of the patient. For example, in some cases it is necessary to he notified about any movements and in others only major movements are of interest. The patient monitoring system is able to provide a flexible means of monitoring of a patient by a nurse or carer.

  • Patent number: 8451129
    Abstract: A unitary patient monitoring system (100) includes an alarm, such as a loudspeaker (203) and a weight sensitive switch (201). Each component is encapsulated in a cover member (101), which can be configured as a T-shape. The alarm is actuated when a user removes his weight from the weight sensitive switch (201). Where the alarm is a loudspeaker (203), an audible alarm is emitted by the loudspeaker (203) when a user gets up off the unitary patient monitoring system (100). Optional features of the unitary patient monitoring system (100) include an interrupt switch (212) for temporarily rendering the alarm inactive and a master switch (211) for turning the unitary patient monitoring system (100) ON and OFF. The unitary patient monitoring system (100) can be configured to turn ON automatically when a user sits on the unitary patient monitoring system (100) as well.

  • Patent number: 8421641
    Abstract: An object detection system, controller, and method using sub-sampling for detecting a presence of an object at the location. An electrode arranged near the location radiates an electric field that corresponds to an electrode signal that arises in response to an excitation signal. When the excitation signal is coupled to the electrode and the electric field is radiated, the electrode exhibits an electrode impedance indicative of the presence of an object. The presence of an object is detected by analyzing the electrode signal using sub-sampling. Traditionally, such electrode signals have frequencies, high enough to warrant the use of expensive high-frequency signal processing devices. Sub-sampling is a way of sampling and processing the electrode signal such that the signal processing to detect the object can be performed by a lower cost general purpose microprocessor.

  • Patent number: 8393432
    Abstract: A seat has a seat frame and a seat cushion supported by the seat frame. The seat cushion has an upper surface that supports a user and a lower surface defining a cavity. The seat cushion moves between an at rest condition in which no operator is seated on the seat, and a deflected condition in which the seat cushion is deflected with respect to the frame in response to an operator seated on the seat. A switch is mounted to the frame and opens and closes an electrical circuit in response to an actuating force. A switch actuator is mounted to the seat cushion lower surface in the cavity and moves between a non-actuating position when the seat is at rest and an actuating position when the seat is deflected. The switch actuator delivers the actuating force as the switch actuator is moved toward the actuating position.
