摘要:
A multi handset telephone system with a wireless telecom/doorbell module. The telecom/doorbell module has similar electronics as a cordless handset that includes audio and RF link with a base unit. A speakerphone functionality of a wireless telecom/doorbell audio processor is used to provide an intercom audio conversation. The wireless intercom/doorbell module is battery powered that is either charged by an AC adapter or by an existing doorbell wiring. The wireless intercom/doorbell module also work in parallel with the existing bell wiring. When a page key is pressed, the module pages the telephone system and shorts the doorbell wiring to make an existing bell ring. The doorbell module is coupled with a camera.

A multimode cordless telephone system that can be used for remote video monitoring. The system includes a base station, at least one camera that is in wireless communication, at least periodically, with the base station, and a cordless handset, having a viewing screen, also in wireless communication, at least periodically, with the base station, the cordless handset having a first mode that is operable when the cordless handset is within a predetermined range of the base station wherein the cordless handset operates in conjunction with the base station to provide telephonic communication and image monitoring of images captured by the cameras, and a second mode that is operable when the cordless handset is beyond the predetermined range of the base station wherein the cordless handset communicates with the base station over the public switched telephone network (PSTN) to monitor images captured by the cameras.
摘要:
An integrated camera, motion detector and cordless telephone system. A wireless camera operates to detect motion and then alerts a user to the motion via a base station/cordless handset. In one embodiment, the camera then also transmits still or streaming video to the base station/cordless telephone. Accordingly, a user can monitor image(s) via a cordless telephone handset and/or be alerted of motion within the camera's field of view.
摘要:
A method for reducing errors in streaming data over a wireless link that aligns data frames with wireless packets. The method is especially suitable for a wireless link that requires a uniform packet size and prohibits re-transmission of packets. One embodiment aligns a start of a data frame with a first wireless packet, transmits a beginning portion of the data frame in the first wireless packet over a wireless link, inserts into a second wireless packet an ending portion of the data frame along with fill data sufficient to fill the second wireless packet, and transmits the second wireless packet over the wireless link. A further embodiment includes synchronization markers at the start of the beginning portion and the ending portion.
摘要:
Systems and methods are provided for routing data messages between a cellular telephone and a cordless telephone system having a plurality of cordless handsets configured to communicate with a single cordless base station when in range. Messages are received at the cordless base station via a first radio frequency transfer protocol. The message is transmitted to the cordless base station from the cellular telephone after the cellular telephone has received the message from a cellular network. The cordless base station transmits the message to a desired one of the plurality of cordless handsets via a second radio frequency transfer protocol. The desired one of the plurality of cordless handsets is chosen based on predetermined message routing settings.
