Abstract: A variable displacement vane pump is described. The pump includes a control chamber provided between a housing and a control slide. A pressure-controlled relief valve is in fluid communication with the outlet path and moves to block or unblock a relief port based on output pressure of the lubricant. A feedback channel fluidly connects the control chamber to an inlet path of the pump. The feedback channel further connects to a control port that is connected to a main control valve. The relief valve and control valve are distinct and not fluidly connected. The relief valve moves once the pressure in the outlet path exceeds a predetermined amount, opening the relief port, and thus delivers a portion of the output lubricant to the control chamber via the relief port, thereby pressurizing the control chamber and reducing eccentricity of the pump by displacing the control slide.

Abstract: There are provided systems and methods for authentication depending on device capabilities and user requests based on situational information collected in advance of a device becoming non-operational. A user may wish to utilize some device process, such as access and use of a device application or other module. For example, a user may wish to utilize a payment application of the communication device, or authenticate the user using a service provider accessible through the communication device. If the communication device becomes non-operational (e.g., lack of power or signal strength), the user may be prevented from authenticating through the communication device. Thus, the user may establish a limited use authentication credential from situational data to the user and device (e.g., location or current image) that allows the user to authenticate with the service provider. The authentication credential may be limited to a location, amount, and/or type of authentication.
