IPC: H01H59/00
Filed: 2000-10-13
Abstract: A dual micro-electromechanical actuator for providing dual actuation to a micromachine. The actuator includes a first substrate upon which a first actuating electrode is formed. A second substrate located proximate to but spaced from the first substrate supports a second actuating electrode. A micromachine device, such as a thin membrane, plate or cantilever, is disposed between the actuating electrodes.  When one of the actuating electrodes is selectively activated by applying a voltage thereto, an electrostatic attraction force is produced which causes movement of the micromachine in the direction of the activated actuating electrode.

Abstract: A duty cycle management system and method for use in a wireless device having a transmitter which transmits packets in the form of individual packets and/or packet bursts comprising a predetermined maximum number of contiguous packets. The transmitter has an associated predetermined duty cycle limit for transmission of packets and is operable over a duration measurable as a series of time windows each of which comprises a predetermined number of timeslots with each timeslot having a predetermined nominal duration. Transmission of one packet occupies one timeslot. A controller in combination with an instruction set limits the number of packets transmitted during each time period defined by one time window or adjacent time windows, on a sliding basis, so as to limit the duty cycle of transmissions during successive adjacent time windows to the predetermined duty cycle limit. To do so transmission of packets is delayed as needed to establish sufficient idle periods) during the one or adjacent time windows) to maintain the duty cycle within the duty cycle limit. An identification is made prior to the transmission of a packet whether an individual packet or a packet burst transmission mode is to be applied. A counter is used in the preferred embodiment for keeping a running count which correlates to the duty cycle over the period of a time window. The counter is incremented by an amount IC for each timeslot in which a packet is transmitted and is decremented by an amount DC for each idle timeslot, whereby the ratio of IC to DC: is the duty cycle limit. Where a maximum count amount, equal to the predetermined number of timeslots per time window, would be exceeded packet transmission is inhibited.
