Patent number: 8724614Abstract: A communications system and protocol for a radio communications network including a number of transceiver devices. The protocol ensures that network variables to be shared by all devices are correctly received and updated by all devices. The protocol also provides for accurately detecting the transition from one time slot to another, in a given data transaction. The protocol utilizes a method of providing a marker in a data time frame for use such as marking the end of a variable slot in a data frame. The method includes encoding data into states, and then generating a marker that is an illegal combination of states in the encoding scheme.Type: GrantFiled: October 13, 2009Date of Patent: May 13, 2014Assignee: Clipsal Integrated Systems Pty LtdInventors: Ashleigh Glen Quick, Donald Murray Terrace

Patent number: 8606279Abstract: A radio frequency communications network system and protocol for allowing the dissemination of data to be shared by devices within a network. The invention is particularly useful when the devices are out of transmission range of each other. The network includes repeater devices located between the devices to manage a data transfer in the network. The invention also provides for data transfer management in the presence of collisions between conflicting data transmissions.Type: GrantFiled: August 9, 2004Date of Patent: December 10, 2013Assignee: Clipsal Integrated Systems Pty Ltd.Inventors: Ashleigh Glen Quick, Donald Murray Terrace

Publication number: 20130208382Abstract: A protection circuit for protecting a dimmer circuit controlling an inductive load including an imbalance detector for detecting an asymmetrical operation in the load and circuit control means for causing the dimmer circuit to reduce a DC component in the load upon detection of the asymmetrical operation. A load imbalance detector is also disclosed having a load DC component detector, a comparator and a signal generating means for generating a circuit shut down signal if the DC component exceeds a pre-set DC threshold.Type: ApplicationFiled: December 26, 2012Publication date: August 15, 2013Applicant: CLIPSAL INTEGRATED SYSTEMS PTY LTDInventor: Clipsal Integrated Systems Pty Ltd

Patent number: 7656793Abstract: A communications system and protocol for use in a non-dominant bit radio network. The radio network includes transceivers which communicate with other transceivers to allow network variables to be shared by all transceivers. The protocol allows the network to handle collisions between competing transmissions from different transceivers. The protocol also handles communications between transceivers that are out of transmitting range of each other.Type: GrantFiled: August 9, 2004Date of Patent: February 2, 2010Assignee: Clipsal Integrated Systems PTY LtdInventors: Ashleigh Glen Quick, Donald Murray Terrace
