Remote control for actuating an electric window shade or an electric window blind or an electric window covering, and method and system of using same. A base unit includes: a wireless receiver, to wirelessly receive from an electronic device an incoming wireless signal indicating a command to actuate an electric window covering; a wireless signal constructor, to dynamically construct an outgoing wireless signal which comprises a rolling code; and a wireless transmitter, to transmit the outgoing wireless signal to a wireless receiver of a motor unit that is operably associated with the electric window covering. A wireless signal constructor dynamically constructs the outgoing wireless signal without having access to a secret seed value that is accessible to the motor unit. A local storage unit stores a data-set of rolling codes that are associated with the motor unit; and the outgoing wireless signal is dynamically constructed based on a next-available rolling code obtained from the local storage unit of the base unit.

Vehicle event recorder systems are arranged to be in constant communication with remote servers and administrators via mobile wireless cellular networks. Vehicle event recorders equipped with video cameras capture video and other data records of important events relating to vehicle use. These data are then transmitted over special communications networks having very high coverage space but limited bandwidth. A vehicle may be operated over very large region while maintaining continuous communications connections with a remote fixed server. As such, systems of these inventions may be characterized as including a mobile unit having: a video camera; a microprocessor; memory; an event trigger; and mobile wireless transceivers, and a fixed network portion including: mobile wireless cellular network, a protocol translation gateway, the Internet and an application-specific server.

摘要:
A vehicle system includes: an in-vehicle apparatus having a signal transmission unit that transmits different pulse pattern signals from multiple transmitting antennas; and a portable device having a receiving unit that receives the signals. The in-vehicle apparatus or the portable device includes a portable device position identification unit that identifies a position of the portable device according to the signals. The portable device includes a frequency-to-voltage conversion unit that outputs a voltage corresponding to a frequency of each signal. The portable device position identification unit includes: a first storage unit that preliminary stores voltage change patterns corresponding to the frequencies of the signals in relation to positions of the vehicle; and a first position estimation unit that compares the voltage change patterns of the frequency-to-voltage conversion unit with the voltage change patterns in the first storage unit, and estimates the position of the portable device.

摘要:
In one embodiment of a system and method for remote activation of a device includes, a transceiver is provided for transmitting a command signal according to a first transmission protocol having a first data rate, receiving an acknowledgment signal indicating that the command signal transmitted according to the first transmission protocol has been received, and transmitting the command signal according a second transmission protocol, the second transmission protocol having a second data rate less than the first data rate and including partition of the command signal. A controller is provided for selecting the first transmission protocol for use in transmitting the command signal in response to a user input, and selecting the second transmission protocol for use in transmitting the command signal when the transceiver fails to receive the acknowledgment signal.
摘要:
The present invention is an interoperable biometrics system that utilizes one or more video communication control devices 32 and/or one or more digital data conversion devices 33 to allow multiple analogue 20 and/or digital 21 output biometric capture devices to communicate with a processing computer 25. The system further incorporates a routing software for addressing and naming the various hardware devices and software systems to enable interoperability between different makes and models and the biometrics capture and/or processing devices, their relevant communications software, and their relevant processing software and algorithms.
摘要:
The present invention includes a communication control device that connects directly to at least one camera. Either analogue or digital cameras are connected to the communication control device. The communication control device captures, compresses, digitizes and/or encrypts the photographic images communicated to the communication control device from each camera and then communicates the processed or compressed images through a TCP/IP or other network protocol to a computer for further processing. The device can further bi-directionally communicate common protocols such as RS232 or RS485 protocols over new or existing computer networks using a TCP/IP or other network protocol. This allows for data input devices such as keyboards, magnetic stripe card readers, proximity readers, barcode scanners, document scanners or similar devices to be interfaced directly into the communication control device. The communication control device can also communicate such protocols to visual output devices such as LCDs to provide interactive feedback on the status or outcome of the verification to the user of the verification system.
