Abstract: A regenerative gate charging circuit includes an inductor coupled to a gate of a FET. An output control circuit is coupled to a timing control circuit and a bridged inductor driver, which is coupled to the inductor. A sense circuit is coupled to the gate and to the timing control circuit, which receives a control signal, generates output control signals in accordance with a first timing profile, and transmits the output control signals to the output control circuit. In accordance with the first timing profile, the output control circuit holds switches or controllable current sources of the bridged inductor driver in an ON state for a first period and holds the switches or controllable current sources in an OFF state for a second period. Gate voltages are sampled during the second period and after the first period. The timing control circuit generates a second timing profile using the sampled voltages.

Abstract: In some embodiments, techniques for managing interaction permissions for an object in a shared virtual environment are provided. The techniques may determine whether to present an object in a limited-interaction mode or in an interactive mode based on a permission condition. The permission condition may include a proximity condition that specifies a proximity threshold between two objects within the shared virtual environment that should be met in order to provide the object in the interactive mode. The proximity threshold may specify a distance between an avatar of an owning user of the object and the object; a distance between an avatar of an owning user of the object and an avatar of a user being presented the object, or other distances.

Abstract: An endpoint system including one or more computing devices presents an object in a virtual environment (e.g., a shared virtual environment); receives gaze input corresponding to a gaze of a user of the endpoint system; calculates a gaze vector based on the gaze input; receives motion input corresponding to an action of the user; determines a path adjustment (e.g., by changing motion parameters such as trajectory and velocity) for the object based at least in part on the gaze vector and the motion input; and simulates motion of the object within the virtual environment based at least in part on the path adjustment. The object may be presented as being thrown by an avatar, with a flight path based on the path adjustment. The gaze vector may be based on head orientation information, eye tracking information, or some combination of these or other gaze information.

The container can also have a receptacle that can be filled with different items for better storage of the contents. The container having a viewer can also have a receptacle that allows the user to still see through the viewer to the contents.

Abstract: Highly secure portable storage device may include a security controller, a data transfer controller and a memory controller. The security controller self-verifies, without a host, an access code. After the verification, the security controller may retrieve a concealed encryption key and a transformation key that were previously self-generated by the security controller. The encryption keys are not generated by the host, a user, or the memory controller. The transformation key is sent to the memory controller via a side channel during a first time period. The concealed encryption key is sent to the memory controller via the side channel during a different time period. After extracting an operating encryption key, the memory controller may notify the data transfer controller to initiate an enumeration process with the host. Data transfer from and to the host is performed via interfaces different from the side channel. Other methods and implementations are also described.

Abstract: Highly secure portable storage device includes a physical input device, a memory and a controller, all of which reside within or on the device itself. The controller may determine whether the device is in an exclusive or nonexclusive mode, whether the device is in a privileged mode, a locked mode or a protected mode, and whether a request is made to self-transform to a renewed mode. When the request is made and the device is in the nonexclusive mode, the device self-transforms to the renewed mode without requiring communication with the host and without requiring access code verification. When the request is made and the device is in the exclusive mode, the device self-transforms to the renewed mode only when a privileged security access code is verified. Transforming to a renewed mode sets all access codes to null and sets a new encryption key. Other methods and implementations are described.

Abstract: In some embodiments, a detecting endpoint system accessing a shared virtual environment detects a collision between a target avatar and an object within the shared virtual environment. The detecting endpoint system transmits a location change notification for a head of the target avatar. An observer endpoint system moves the head of the target avatar based on the location change notification. A target endpoint system associated with the target avatar does not move its viewpoint based on the location change notification. In some embodiments, this decoupling of viewpoint from the avatar allows for a more immersive experience for all users.

Abstract: In some embodiments of the present disclosure, endpoint systems participating in a shared virtual environment simulate objects locally that a user of the endpoint system is likely to interact with. In some embodiments, object authority is thus managed by the endpoint systems, and is not managed by a central server. In some embodiments, a subsequent endpoint system likely to interact with an object may be predicted, and object authority may be transferred to the subsequent endpoint system before the interaction in order to provide an immersive experience for a user of the subsequent endpoint system. In some embodiments, efficient techniques for transmitting notifications between endpoint systems are provided.

Abstract: A portable storage device can convert itself, without a host computer, from being a fixed disk to a removable disk and from being a removable disk to a fixed disk. The storage device may include a physical input device, a memory and a controller. The controller may determine, based on information stored within the storage device, whether the storage device is currently a fixed disk or a removable disk. The controller may then convert the storage device to a removable disk or a fixed disk, based on a control input and the determination. The control input may be received from the physical key input device. When the storage device is a removable disk and when a command from a host computer requests ejecting a memory within the storage device, the controller declines the request and instead electrically disengages the storage device from the host computer.
