Abstract: Circuits for providing overcurrent protection are disclosed herein. The circuits feature depletion mode MOSFETs connected to resistive elements, preferably, Positive Temperature Coefficient (PTC) devices, configured in such a way so that the voltage across the PTC device is the same as the gate-to-source voltage of the MOSFET. The circuit may further be configured using a TVS diode, for clamping the drain-to-source voltage of the MOSFET during the overcurrent events. Heat transfer between the MOSFET and the PTC device facilitates overcurrent protection. A two-terminal device including a depletion mode MOSFET, a PTC device, and a TVS diode may provide overcurrent protection to other circuits. A bidirectional circuit c including two MOSFETS disposed on either side of a PTC is also contemplated for AC voltage overcurrent protection.

Abstract: A networked sales method is disclosed that includes presenting price choices to a user for an item on a sales screen via a network. Available supply and sales activity level information about actions by other users for the item for which the price choices are presented can be converted into a feedback indication, and this indication can be conveyed to the user on the sales screen. A variable price schedule for the item can also be communicated to the user, and a reminder command associated with an entry in the schedule can be received from the user, with the reminder command including a price selection for the item. The user can then be notified when the entry in the schedule is reached.

Abstract: Some embodiments include a networked sales method. The method includes presenting, via a first network, item information associated with an item on a sales screen to a user. The method also includes communicating a variable price schedule for the item to the user. The variable price schedule includes a plurality of price selections for the item. The method includes receiving a reminder command associated with a selection of an entry in the variable price schedule from the user. The reminder command includes a price selection from the plurality of the price selections for the item. The method includes notifying the user when the entry in the variable price schedule is reached.

Abstract: A method and apparatus for concurrently displaying from a single window on a network management station the health status of all network devices and objects of a computer network. The network devices may be categorized according to state or device type, as determined by the network manager. The method and apparatus provides a network manager with the ability to determine the current state of network devices and objects within an enterprise network and invoke further actions such as configuration, performance, fault, and security management tasks. The network manager can drag and drop icons from one network management system application window to another network management system application window to obtain fault information about network devices and objects, thus allowing multiple network management system applications to run concurrently on the same network management station.
