  • Patent number: 11972451
    Abstract: A system for customizing an end user gaming experience is disclosed herein. The system includes a processor. The processor is configured to create a campaign by receiving a campaign creation request from an end user device, the campaign creation request comprising one or more parameters of a campaign associated with the campaign request, creating the campaign based on the one or more parameters associated with the campaign request, and personalizing one or more offers for an end user, each of the one or more offers comprising a game having one or more hurdles, wherein completion of each of the one or more hurdles leads to a reward. The processor is further configured to map a subset of the one or more personalized offers to the end user. The processor is further configured to monitor progress of the campaign.

  • Patent number: 4119016
    Abstract: A hydraulic control device for use in a hydraulic system having a pump supplying fluid from a reservoir to a working circuit. The control device detects leaks in the working circuit by monitoring the level of hydraulic fluid in the reservoir. In the event of a drop in the level of hydraulic fluid beyond a predetermined low level, the control device automatically diverts the fluid output side of the pump to the fluid input side to prevent further loss of fluid in the working circuit and to safeguard against cavitation in the pump due to the low level of fluid in the reservoir. The control device also senses excessive pressure peaks in the working circuit and operates to relieve the excessive pressure peaks by automatically venting a portion of the fluid on the output side of the pump to the reservoir.

  • Patent number: 3994133
    Abstract: In a hydraulic power system having two independent circuits, wherein one circuit has priority over the other circuit, and the priority circuit furnishes a residual flow to the non-priority circuit, a pressure sensing system is provided in the return flow line of the non-priority circuit which causes a directional flow valve to shift and direct the residual flow back to the priority circuit in the event of a leak in the non-priority circuit which results in a loss of pressure in the return line.
