Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel at the home of a patient under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by allowing the remotely located imaging expert to enable or disable the transmission of ultrasound energy by the ultrasound system. Other functions of the ultrasound system may also be controlled by the remotely located expert, such as determining whether acquired ultrasound images can be viewed locally on the ultrasound system.

Abstract: A method and corresponding system is disclosed for use in a Networked Lighting Control System whereby communication costs (e.g. costs associated with LTE technologies), variable electric rates and traffic models are analyzed to maximize cost savings. In one example, the system consists of receiving cellular usage rates, electric usage rates, and generated traffic models or statistics to manage transmission and broadcast of usage rates to lighting poles. An apparatus associated with the lighting pole can then use this information to determine frequency of sending lighting commands to nearby poles.

Abstract: This invention provides systems and methods to make communication networks more resilient, stealthier and robust. This invention discloses systems and methods wherein either a communications user equipment (UE) with multiple types of wireless links, potentially operating in different frequency bands, or an apparatus which performs communications routing functions, changes the communications routing in pseudo-random manner.

Abstract: A system for alterting heathcare practitioners (20) includes a plurality of receiving devices (10), and a sending station (30). Each of the plurality of receiving device is associated with a corresponding healthcare practitioner. The receiving device (10) includes a user alerting device (120), a receiver (110), and circuitry (160). The user alerting device (120) alerts the practitioner to a received message with one of a plurality of types of alerts. The receiver (110) receives the incoming messages. The circuitry (160) causes the user alerting device to alert the practitioner to an incoming message with one of the plurality of types of alerts.

Abstract: A method and system to extend the coverage of Outdoor Lighting Networks (OLNs) through the use of authorized mobile devices travelling around to establish a virtual connectivity link (i. e., storing data and, when in reach, using short-range wireless communication protocols) between isolated light points (or groups of light points) and connected light points so that lighting commands and data can be exchanged between the two sets of lighting points is disclosed.

Abstract: In order to better and more easily identify candidate APs and/or channels, an AP can transmit frames announcing its capabilities in a channel where it is not serving. For example, if an AP is operating in channel 1 and has created a Basic Service Set ID (BSSID) in that channel, it is permitted to transmit frames announcing its capabilities in another channel, for example channel 3, where another AP may or may not be operating.

Abstract: A wireless system includes a plurality of objects. The wireless system includes a controller and a radio frequency identification (RFID) read-write device. Each of the objects includes an RFID device and a transceiver. An object and methods of tracking objects are also disclosed.

Abstract: A patient monitor includes least one monitoring device which collects patient data about a patient. A packet generator generates data packets from the patient data collected from the patient. A communication unit transmits the data packets over an Internet protocol (IP) network. The communication unit includes a first transmitter for transmitting the data packets using a first wireless network and a second transmitter for transmitting the data packets using a second wireless network.

Abstract: A patient monitor includes a plurality of monitoring devices which collect data about a patient. An evaluation unit determines the patient's condition from the collected data and generates an alarm if the patient's condition warrants notifying an appropriate medical responder. A communication unit which transmits the alarm to a access point over a hospital Internet protocol (IP) network, the communication device includes a first transmitter for transmitting the alarm using a primary link and a second transmitter for transmitting the alarm using a secondary link in response to the transmission using the primary link failing.

Abstract: A wireless local area network (WLAN) includes a first device and a second device. The first device sends a first frame including a first transmission indicator, which indicates that a service interval is to begin at a certain time. The second device sends an acknowledgement from the second device to the first device indicating receipt of the first transmission indicator. The first device sends a second frame including another first transmission indicator if, after a prescribed time period, the acknowledgement is not received by the first device. The first device also sends a last transmission indicator, which indicates that the service period will end at a certain time. The WLAN and its method of use provide synchronicity between the first and second devices as to the beginning and the end of a service period.
