Patent number: 9905238Abstract: A base station for use in a communication system is configured to determine whether a set of access information provided by an end unit is acceptable to the base station. The access information facilitates identification by the base station of one or more codecs used by the end unit to encode and decode digital audio signals. Other end units may use different codecs to encode and decode digital audio signals. The base station is configured to simultaneously handle multiple different codecs. The communication system also comprises at least one end unit configured to determine the codec used by the base station, request registration to the base station, and set the determined codec as the codec to use for communications with the base station.Type: GrantFiled: October 31, 2016Date of Patent: February 27, 2018Assignee: HM Electronics, Inc.Inventor: David O'Gwynn

Patent number: 9639906Abstract: This disclosure relates to a quick service restaurant intercom communication system. The system is configured such that communication between a customer and a staff member is accomplished in wideband audio. Intercom communication systems that utilize narrow band audio for communication between drive-through customers and staff members may be considered “good enough”. However, the low fidelity sound produced by narrow band audio systems often results in misunderstandings between customers and staff members, a high amount of background noise during communication, and/or other negative effects. Wideband audio may facilitate clearer communication between customers and staff members. Wideband audio communication may be costlier and/or more complicated to implement, but may result in increased staff efficiency and/or increased customer satisfaction.Type: GrantFiled: March 12, 2013Date of Patent: May 2, 2017Assignee: HM Electronics, Inc.Inventor: David O'Gwynn

Patent number: 9484041Abstract: A communication system with a base station configured to determine a codec to use with end units, such that, in response to a determination that a first end unit uses a first set of access information, the base station registers the first end unit to the base station, setting the first codec to be used for communications with the first end unit, and, in response to a determination that a second unit uses a second set of access information, the base station registers the second end unit to the base station, setting the second codec to be used for communications with the second end unit. The communication system also comprises an end unit configured to determine the codec used by the base station and set the determined codec as the codec to use for communications with the base station.Type: GrantFiled: September 25, 2014Date of Patent: November 1, 2016Assignee: HM Electronics, Inc.Inventor: David O'Gwynn

Patent number: 9443275Abstract: A system and method for facilitating ordering at an order point using a smart ordering device are disclosed. A primary transmitting device and a secondary transmitting device may be positioned opposite of one another at the order point. A short distance linkage may be established between the primary and secondary transmitting device. A disruption of the linkage may be detected when an object carrying a smart ordering device passes through the order point. Information indicating the disruption may be included in a signal transmitted by the primary transmitting device to the smart ordering device. Based on such information and the signal strength of the signal from the primary transmitting device, the smart ordering device may determine it is at the order point. In response to such determination, the smart ordering device may generate and communicate an order request to a remote server for placing an order.Type: GrantFiled: February 20, 2014Date of Patent: September 13, 2016Assignee: HM ELECTRONICS, INC.Inventor: David O'Gwynn
