Abstract: A wiper including wiper bracket which couples a wiper arm to blade carrier which carries one or more blades and includes an internal flow path which conducts fluid from a wiper bracket inlet through a hollow passage in a wiper blade carrier cover to plurality of outlets aligned with passthroughs in the blade carrier through which fluid egresses from the wiper.

Abstract: A battery system includes a battery module, an active cell balancing circuit, and a battery controller. Each cell has diametrically-opposed positive and negative cell tabs. The circuit includes voltage sensors and, at each end of the battery module, first and second tiers of switches and an energy storage element. Each voltage sensor is located between a different pair of adjacent cells. The controller receives measured voltages from the sensors indicative of an electric potential between adjacent battery cells. Responsive to the measured voltages, the controller commands the first tier to selectively connect or disconnect designated pairs of cells to the corresponding second tier. The controller also commands the second tier to selectively connect or disconnect the designated cells to a corresponding energy storage element. This action shuttles energy between the designated pairs of battery cells to balance a state of charge.

Abstract: Methods and apparatuses are described herein for improved communications between a service and end devices via a gateway. A token may be in a signed encrypted state when sent to untrusted devices and may be signed, but not encrypted, when used by trusted devices. Untrusted devices may receive the encrypted token and may use it to access services. An untrusted device may send the received encrypted token to the gateway, which may then send the token to its issuer so that the token issuer may decrypt the data payload. The token may then be sent back to the gateway, which may then read the decrypted data and verify whether the untrusted device is permitted to access the requested service. The gateway may then send, within the trusted domain, the request and token to the service provider so that the untrusted device can obtain access to the requested service.

Abstract: A computer-implemented method in a content delivery network (CDN), wherein the CDN delivers content on behalf of at least one content provider. The CDN includes a rendezvous system that selects CDN servers for clients. In response to a request by a rendezvous mechanism in the rendezvous system, a first given function is evaluated. Based on the outcome of the evaluating, the rendezvous mechanism uses either a first table or a second table. The first table was generated by a first table generation mechanism for use by said rendezvous mechanism to select CDN servers for clients, and the second table was generated by a second table generation mechanism for use by the rendezvous mechanism to select CDN servers for clients.

Abstract: An example method involves accessing a playlist defining a sequence of media content items including a first media content item and a second media content item; retrieving, from one or more server devices, first data representing the media content items of the received playlist, and using the retrieved first data to playout the media content items in accordance with the sequence defined by the playlist; determining a status of an event, and using the determined status of the event as a basis to determine a condition; making a determination that the determined condition has been satisfied; and responsive to making the determination that the determined condition has been satisfied, (i) retrieving second data representing a media content item related to the event, and (ii) using the retrieved second data to playout the media content item related to the event in between playing out the first and second media content items.

Abstract: A policy control function (PCF) receives a first message from an application function (AF). The first message comprises: an always-on PDU session requested indication; an identity of a wireless device; and application service information. The PCF maps, based on the first message, the application service information to an always-on PDU Session for the wireless device. The PCF sends to a session management function (SMF), at least one policy and charging rule for the always-on PDU Session.

Abstract: A system for treating an aneurysm in a blood vessel or vein, wherein the aneurysm has a dome, an interior, and a neck. The system includes a shape memory polymer foam in the interior of the aneurysm between the dome and the neck. The shape memory polymer foam has pores that include a first multiplicity of pores having a first pore size and a second multiplicity of pores having a second pore size. The second pore size is larger than said first pore size. The first multiplicity of pores are located in the neck of the aneurysm. The second multiplicity of pores are located in the dome of the aneurysm.

Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

Abstract: A staple gun and a method of using the same. A stapling mechanism in the housing is activated to deliver a staple through an aperture in a housing wall and drive the staple into a surface around a stack of one or more electric cables. The gun includes a reciprocating cable guide for centering the gun on the stack of cables and closing a safety switch to permit the gun's trigger to be activated. A spacer extending outwardly from the housing wall rests on the upper surface of the cable stack. The spacer and a bumper that engages a hammer of the stapling mechanism provide for automatic depth adjustment when driving the staple into the surface. A reciprocating cable guard extending outwardly from the housing wall is positioned between the stack of cables and the staple to aid in preventing the staple from piercing the cable.
