Abstract: Pluralarity of network controlled retail display receiver is attached to the shelf carrying items whose information such as price and other attributes need to be displayed. The display receiver wakes up to see the information change bit indicator and its addresssed group. If detected, receiver captures the packet, decodes it and rrefresh its man machine interface. The receiver gets command from the controller either placed in the store or through digital terrestrial/satellite broadcast networks. The invention allows consistant management of similar items information placed in retail stores of same franchise, geographically apart.

Abstract: An addressable embedded transceiver lock (ETL) is proposed. The ETL is equipped with a network access interface (wired or wireless), subscriber serial data interface (wired or wireless), man machine interface and a command decoder. The network access interface is used to communicate with the remote service gateway the subscriber serial data interface is used to communicate with the subscriber home loop and a command decoder is used to take actions as constructed by the remote gateway. When ETL is powered, it first registers with the remote service gateway (a call center or owner of the unit) over a wide area network (wired or wireless). The service gateway maintains profile of the installed ETL and it's communicating capabilities. Upon demand by the remote attendant, the ETL performs operations such as lock open, lock close, lock status. ETL may also alert the service gateway of activities as predefined. Various derivatives of ETL may include Motion Sensor, Camera.

Abstract: Real Estate properties for sell show are vulnerable to misuse, especially if key is placed in a mechanical lock box. System and method is proposed to validate the caller as being a real estate sales associate. The proposed system is always updated with active agent's roster identities. Some scenarios of updates are: when real-estate commission issues a license, when a licensee joins a broker office, and when a licensee changes sub-broker office, when he becomes a referral source or if his license is suspended, revoked. Methods are discussed in which access is made available to an agent sitting in the broker allocated call centers. When a caller calls, to the broker (sub-broker) call center for inquiring about sell show, the proposed system from the calling number identification data makes a search in the agent roster repository. Actions are taken based on yah nay.
