Abstract: An improved twin clutch, two-speed disconnect secondary drive unit, which may be configured as a rear drive unit (RDU) for an all wheel drive vehicle is provided. The RDU is driven through an input shaft, which is connected to a vehicle drive source such as a motor, and includes a twin clutch assembly, which is connected to the drive shaft and is selectively actuated to drive left and right main shafts, which drive respective wheels of the vehicle. The RDU further includes a modular a shift assembly mountable to one or both of said main shafts to drive output shafts, wherein each shift assembly is selectively operable between the hi-range and lo-range modes to shift driving operation of the output shafts between hi-speed and lo-speed operation. The shift assembly may be controlled by improved mono-stable or bi-stable actuators.

Abstract: A locking differential assembly includes a differential case, a first output shaft and a second output shaft. A first side gear is non-rotatably coupled to the first output shaft and a second side gear is non-rotatably coupled to the second output shaft. A differential pin is also included, the differential pin having differential gears. The differential gears are rotatably supported by the differential case and drivingly engaged with the first and second side gears to allow differential rotation thereof. A lock mechanism is actuated when a first torque force is applied to a drive cam and a driven cam. Finally, an electromagnetic coil actuates a brake plate, wherein the brake plate comes into frictional with a brake disc. Furthermore, the electromagnetic coil is discontinuous around the circumference of the brake disc.

Abstract: Piston apparatus for use with vehicle clutches are disclosed. A disclosed drive unit assembly for a vehicle includes a housing defining a first cavity and a second cavity fluidly coupled together. The drive unit assembly also includes a clutch positioned in the first cavity. Rotation of the clutch conveys a fluid from the first cavity to the second cavity. The drive unit assembly also includes a port extending from the second cavity to the first cavity to receive the fluid. The drive unit assembly also includes a piston positioned in the first cavity proximate to the port and configured to operate the clutch. Movement of the piston relative to the port controls a flow of the fluid through the port from the second cavity to the first cavity.

Abstract: Systems, apparatus, and methods to control fluid associated with vehicle clutches are disclosed. A disclosed apparatus includes a drive unit assembly for a vehicle. The drive unit assembly includes a housing and a clutch in a cavity of the housing. Rotation of a drum of the clutch expels a fluid from the cavity. The apparatus also includes a vehicle controller configured to disengage the clutch via an actuator. Actuation of the actuator reduces a flow of the fluid into the cavity. The vehicle controller is also configured to maintain engagement of a vehicle transfer device operatively coupled between a vehicle transmission and the drum such that the drum continues to rotate for a time interval during which the clutch is disengaged.

Abstract: User interface information related to relevant events of interest is provided. Events can occur anywhere in a document, and may or may not be relevant to a user utilizing an assistive technology (AT) application, such as a screen reader. A provider-side signaling system component determines whether raised events are relevant to the user. In some examples, when an application makes a plurality of attribute changes in a document at once, the signaling provider batches the related events as a single transaction, and generates a generalized annotation describing the changes. The signaling provider further packages the event notification, and sends the event notification to a client-side signaling system component. The signaling client receives the notification, and determines whether to alert the user of the event(s) based on verbosity settings. The AT application is enabled to interpret the event notification and alert the user in a meaningful way.

Abstract: Using declarative language application instructions, actions associated with playing interactive content of an interactive multimedia presentation are triggered based on a state change of a particular media object. Certain application instructions specify the characteristic of the media object, while other application instructions specify the actions associated with playing the interactive content (for example, when media objects are renderable, event generation, script execution, or changes in variables) based on a state change of the characteristic. The state change is detected by querying a structured representation of the application such as a document object model, which includes nodes associated with the application instructions, the media object, and/or the characteristic. When state changes are detected, one or more of the specified actions are triggered to thereby declaratively respond to the state change.

Abstract: An interactive multimedia presentation has a predetermined presentation play duration, a video content component (which may include video, audio, data, or any combination thereof), and an interactive content component. Methods and systems for playing the presentation include specifying a time when a particular media object is renderable. The time is specifiable using an application instruction that references either a first timing signal having a rate that is based on the play speed of the presentation, or a second timing signal having a continuous rate. One example of an application instruction usable as described above is an element associated with an XML data structure. An attribute of the element, such as the clock attribute, may be used to provide time values for the element that reference either timing signal. The attribute is used to maintain frame-accurate synchronization between the video and the interactive content components of the presentation.

Abstract: An interactive multimedia presentation playable by a presentation system includes a media content component and an interactive content component. The interactive content component includes one or more applications, which provide instructions for organizing, formatting, and synchronizing the presentation of interactive objects to a user. Prior to playing the interactive multimedia presentation, an entity responsible for authoring or publishing one or more of the applications is digitally identified and authenticated, or it is determined that the applications are unsigned. Prior to and/or during play of the interactive multimedia presentation, authorization for performing certain actions (such as executing certain application instructions, especially those that access functionality of the presentation system, computer-readable media, or external networks) is granted via a permission-based model.

Abstract: Systems and methods of the present invention provide for detecting and mitigating abuse of undeliverable email or “bounced” emails. An administrator may import a list of email addresses for one or more contacts. The opt-in software may determine if each email address in the list of email addresses is opted in to receive an email distribution, and if so, a bounce detection software may determine if each email address is found in a database of known undeliverable or “bounced” email addresses. If so, an abuse-mitigation software may defer importing the list of email addresses and display an alert referring the administrator to an abuse department for review of the account.

Abstract: Braille symbols are automatically read aloud, to aid in learning or using Braille. More generally, a tile which bears a tactile symbol and a corresponding visual symbol is placed in a sensing area, automatically distinguished from other tiles, and vocalized. The tile is sensed and distinguished from other tiles based on various signal mechanisms, or by computer vision analysis of the tile's visual symbol. Metadata is associated with the tile. Additional placed tiles are similarly sensed, identified, and vocalized. When multiple tiles are placed in the sensing area, they are vocalized individually, and an audible phrase spelled by their arrangement of tactile symbols is also produced. A lattice is provided with locations for receiving tiles. Metadata are associated with lattice locations. Tile placement is used to control an application program which responds to tile identifications.

Abstract: Systems and methods of the present invention provide for detecting and mitigating abuse of unsolicited email or “spam.” An administrator may select one or more contacts from a list of contacts to opt in to receive an email distribution. An abuse detection software may then determine for each contact in the contact list whether the contact has read the email distribution and reported the email distribution as an unsolicited email message. If so, an abuse department may place a hold on the email distribution (possibly using abuse mitigation software) and display an alert referring the administrator to the abuse department for review of the account. Otherwise, the email distribution may continue to completion.

Abstract: A touch screen input device is provided which simulates a 3-state input device such as a mouse. One of these states is used to preview the effect of activating a graphical user interface element when the screen is touched. In this preview state touching a graphical user interface element on the screen with a finger or stylus does not cause the action associated with that element to be performed. Rather, when the screen is touched while in the preview state audio cues are provided to the user indicating what action would arise if the action associated with the touched element were to be performed.
