摘要:
An electrostatically actuated micro-mechanical switching device with movable elements formed in the bulk of a substrate for closing and releasing at least one Ohmic contact by a horizontal movement of the movable elements in a plane of the substrate. The switching device has a drive with comb-shaped electrodes including fixed driving electrodes and movable electrodes. A movable push rod is mechanically connected with the movable electrodes, extends through the electrodes, has a movable contact element at one side, and at least one restoring spring. A signal line has two parts interrupted by a gap. The micro-mechanical switching device is in shunt-configuration with low loss, high isolation in a wide frequency range, low switching time at low actuation voltage and sufficient reliability. The line impedance of the signal line and its variation is as small as possible. The switching device is in shunt-configuration for closing and releasing the Ohmic contact between a ground line and the signal line. The contact element has a movable contact beam extending at least partially opposite to the signal line and being electrically and mechanically connected to both parts of the signal line, respectively. The ground line is formed with a contact bar that leads through the gap of the signal line for forming the Ohmic contact between the contact beam and the ground line. A contact metallization is provided at least on top and on the side walls of the contact beam, of the signal line and of the ground line.

According to one embodiment, a scheduling apparatus sends queries to communication modules in buildings and receives facility information measured at monitor-control points from the communication modules. As for each communication module, a network address, a waiting time to receive the facility information after sending a query, and a connection with the monitor-control points, are stored. When a service request indicating at least one monitor-control point is received, queries each including the network address of a communication module connected with a monitor-control point indicated by the service request, are generated. A priority of each query is decided based on the waiting time corresponding to the communication module. Each query is added to a first send queue or a second send queue based on the priority. When queries are sent, a timing to send from the first send queue is same as or earlier than a timing to send from the second send queue.

A humidity estimation device connected with an air-conditioner includes a charge airflow rate estimation (CARE) unit, a charge air absolute humidity estimation (CAAHE) unit, an indoor generated vapor amount estimation (IGVAE) unit, and an indoor absolute humidity estimation (IAHE) unit. The CARE unit calculates an estimated charge airflow rate (ECAR) of the air-conditioner based on operation control information of the charge fan and a preset fan differential pressure. The CAAHE unit calculates an estimated charge air absolute humidity (ECAAH) of the air-conditioner based on a charge air temperature and a preset charge air relative humidity. The IGVAE unit calculates an estimated indoor generated vapor amount (EIGVA) based on an indoor temperature, the number of persons in the room and activity index values of the persons. The IAHE unit calculates an estimated absolute humidity in the room based on the ECAR, the ECAAH and the EIGVA.
