Patent number: 10963846Abstract: This disclosure describes, in part, techniques for automated integration between services provided by a service provider. The techniques described herein employ classifiers to determine whether items offered for sale by a merchant are services or goods. A service-identification model may receive names of items as inputs, and be trained or otherwise configured to output indications of whether the names of the items correspond to services. In some examples, the names of the items which correspond to services may further be input into a duration-identification model, which is trained or otherwise configured to determine periods of time required by the merchant to perform the services. The techniques described herein may include populating user interfaces, such as a merchant website, with indications of the services, as well as periods of time to perform the services, that customers may interact with to schedule appointments with the merchant.Type: GrantFiled: October 31, 2017Date of Patent: March 30, 2021Assignee: Square, Inc.Inventors: Lee Cunliffe, Edmond Chan

Patent number: 6263194Abstract: An apparatus and method to use the temperature of a transmitting radio to prevent transmission of radio waves outside of an assigned frequency band. More specifically, if a transmitter exceeds a specified temperature the transmitter will be automatically disabled to prevent temperature caused frequency shifts outside the approved frequency transmission band for the transmitter. The transmitter has a temperature sensor that senses temperature and compare the operating temperature against a preselected temperature limit. It the operating temperature either is too hot or too cold the transmitter will be disabled and will not transmit until the temperature falls or rises to an acceptable level.Type: GrantFiled: July 17, 1998Date of Patent: July 17, 2001Assignee: RadioShack CorporationInventors: Edmond Chan, Vincent Lam
