Abstract: Aspects of the present disclosure relate to systems and methods for creating a file activity feed for display on a user interface of a client computing device. In one aspect, data comprising a plurality of activities associated with a file may be obtained. A timestamp associated with a user identity of the file may be identified. One or more missed activities (e.g., those that occurred since a user was away from the file) may be identified from the plurality of activities based on the identified timestamp. It may be determined which missed activities of the one or more missed activities are relevant to a user associated with the user identity. The one or more missed activities determined to be relevant to the user associated with the user identity may be displayed within the file activity feed on the user interface of the client computing device.

Abstract: Aspects of the present disclosure relate to a unified activity service. In one aspect, a first file stored on a first storage platform may be rendered on a first user interface. One or more activities associated with the first file may be obtained from the activity service. A second file stored on a second storage platform may be rendered on a second user interface. One or more activities associated with the second file may be obtained from the activity service. In another aspect, activity metadata corresponding to at least one activity associated with a first file stored on a first storage platform and activity metadata corresponding to at least one activity associated with a second file stored on a second storage platform may be received at and stored in the activity service.

Abstract: An electrical cable connector has a body having first and second body members that are movable between open and closed positions of the body, and first and second conductors supported by the first and second body members, respectively. The two conductors have respective ends protruding from the respective body members. When the body members are moved to the closed position of the body, the ends of the conductors simultaneously cut through insulation and come into electrical connection with two cores of a first cable. A connecting element electrically connects the conductors to respective cores of a second electrical cable.

Abstract: An electrical switch has a casing, fixed and moving contacts, and an internal operator turning and moving the moving contact relative to the fixed contact for switching.

Abstract: A protection circuit limits operating power supplied to an electrical device from an electrical power source below a predetermined power rating. The protection circuit comprises a switching device for adjusting electrical power supplied from the power source to the electrical device; a sensor sensing a parameter relating to the operating power; and a comparator comparing the parameter sensed by the sensor and, in response to identifying an undesirable operating condition, controlling the switching device to adjust electrical power supplied to the electrical device to below a predetermined power rating.

Abstract: An electrical rotary switch has a rotor with a periphery, a moving contact on the rotor and several connected parts adjacent the rotor periphery, and four fixed contacts around the rotor for short-circuiting by the moving contact. Each fixed contact has first, second, and third integrally connected sections. The first section bears resiliently against the rotor periphery for sliding contact with the moving contact parts. The second section turns through an angle larger than 135° from the first section. The third section turns through an angle smaller than 90° from the second section for connection of an electrical cable by self-gripping. The moving contact has an undulating profile matching with that of an adjacent part of the rotor periphery.

The nonlinear pulse generator is characterized by its transfer characteristic which has alternating stable and unstable operating regions. The pulse width modulated signal is generated by varying the operating point between among the unstable and stable operating regions.
