Patent number: 12084104Abstract: This disclosure describes, in part, a mobile apparatus for identifying items within a facility using an omnidirectional imaging system. For instance, the mobile apparatus may include a main frame, a chassis attached to the main frame, a basket that attaches to the chassis in order to prevent the basket from contacting the main frame, and an omnidirectional imaging system providing image data in and around the mobile apparatus. A user may place item(s) within a receptacle of the basket. The mobile apparatus may further include a handlebar module attached to the main frame, the handlebar module including the omnidirectional imaging system and a computing system for identifying items and events in and around the cart.Type: GrantFiled: December 6, 2021Date of Patent: September 10, 2024Assignee: Amazon Technologies, Inc.Inventors: Rachid M Alameh, Stephen Ernest O'Dea

Patent number: 11994928Abstract: This disclosure describes, in part, a mobile apparatus that includes capacitive sensor(s) for detecting the presence of a user. For instance, the mobile apparatus, such as a shopping cart, may include capacitive sensor(s) located proximate to a main frame, the handles, and/or the wheel frame. The mobile apparatus may use one or more of these capacitive sensor(s) to determine that the user is located proximate to the mobile apparatus, in contact with the mobile apparatus, and/or located over the main frame of the mobile apparatus. In some examples, the mobile apparatus may then perform one or more actions based on the presence of the user. For example, the mobile apparatus may activate and/or deactivate one or more devices based on the presence of the user. This way, the mobile apparatus is able to conserve power by using the capacitive sensor(s) to detect the present of the user.Type: GrantFiled: April 7, 2021Date of Patent: May 28, 2024Assignee: Amazon Technologies, Inc.Inventors: Rachid M Alameh, Andre David Brown, Gopi Prashanth Gopal, Stephen Ernest O'Dea

Patent number: 10471849Abstract: A circuit breaker/disconnector apparatus for use in a power delivery system comprises a unidirectional DC circuit breaker which has a first terminal and a second terminal and is configured to automatically open during an overcurrent condition in a forward direction and to remain closed independent of current level in a reverse direction. A disconnector switch is in series with the circuit breaker. The disconnector switch has a first terminal for connecting to a first polarity connector of a power supply, a second terminal for connecting to a second polarity connector of the power supply and a common terminal connected to the first terminal of the circuit breaker. The disconnector switch has at least a first position in which the first terminal is connected to the common terminal and a second position in which the second terminal is connected to the common terminal.Type: GrantFiled: November 3, 2015Date of Patent: November 12, 2019Assignee: Hawker Siddeley Switchgear LimitedInventor: Stephen Ernest Lane

Publication number: 20190244613Abstract: A VoIP server may provide voice-based services when a VoIP device dials a preconfigured number (e.g., “##999”). Similarly, a VoIP device having an additional display and/or function keys may signal that a voice-command communications channel should be opened between the VoIP device and the VoIP server in a different way (e.g., using a dedicated button). The VoIP server recognizes the number being called as a request for voice-based services as it would recognize a call to a voicemail extension as a request for voicemail services. Thus, the VoIP server intercepts the outgoing call and directs the call to itself to begin providing voice-based services (e.g., voice dialing and calendaring services).Type: ApplicationFiled: February 1, 2019Publication date: August 8, 2019Applicant: Net2Phone, Inc.Inventors: Samuel Joshua Jonas, Simon Malcolm Ritholtz, Nathaniel Ernest Ritholtz, Stephen Ernest Gulics, Elena Marie Papavero, Anthony S.
