Abstract: A health service system for caring for the health of a patient. In one example, the health service system operates to present media content in association with a telehealth consultation. The health service system generates a virtual waiting room for display on a patient device, which presents a media content presentation. After the media content presentation has concluded, the health service system facilitates the telehealth consultation between a patient and a care provider. In some configurations the health service system further includes at least one hub care facility. The hub care facility includes a locked door with a scanner that unlocks the locked door upon scanning a time sensitive door unlock code; and a locked medication locker with a scanner that unlocks the locked medication locker upon scanning a medication locker unlock code.

Abstract: A crossbow includes a stock defining a projectile axis, a drawstring configured to move along the projectile axis between an undrawn position and a drawn position, the undrawn position defining a first power stroke end, the drawn position defining a second power stroke end, and a scope rail mount including a first support and a second support, the first support coupled to the stock at a first mount location positioned rearward of the first power stroke end, the second support coupled with the stock at a second mount location positioned rearward of the first mount location and forward of the second power stroke end.

Abstract: Systems and apparatuses include a crossbow having a stock, a vertical limb, a hub, a mid support. A projectile plane defines a projectile axis within the projectile plane. The vertical limb includes a first end and a second end. The first end is coupled to the stock by a main support positioned vertically below the projectile axis. The second end is positioned vertically above the projectile plane. The hub is rotatably mounted to the stock and includes a first portion and a second portion positioned axially between the stock and the first portion. The first portion is operatively coupled with the vertical limb. The mid support is coupled to the stock. The mid support is configured to support the vertical limb between the first end and the second end.

Abstract: A crossbow includes a stock having a first side and a second side. The stock defines a projectile flight path. The crossbow includes a scope rail mount. The scope rail mount includes a first support and a second support. The first support is coupled with the first side of the stock. The second support coupled with the second side of the stock. The scope rail mount configured to straddle the projectile flight path.

Abstract: A crossbow includes a frame including a riser, a first and a second cam, a first and a second flexible limb, a first power cable, a second power cable, and a drawstring. Each cam has a larger diameter portion and a smaller diameter portion. The first power cable has a first end attached to a mounting position on the riser and a second end attached to the smaller diameter portion of the first cam. The second power cable has a first end attached to a mounting position on the riser and a second end attached to the smaller diameter portion of the second cam. The drawstring is attached to the larger diameter portion of the first cam and the larger diameter portion of the second cam. The drawstring wraps at least one full wind around the larger diameter portions of the cams when the crossbow is undrawn.

Abstract: A crossbow is configured to shoot a projectile. The crossbow includes a frame having a stock positioned at a rear end, the frame defining a horizontal projectile plane at a top side in which a projectile axis is positioned. The projectile moves within the horizontal projectile plane and along the projectile axis during firing and arming of the crossbow, and the projectile is fired from a front end of the frame. The crossbow further includes a drawstring hub connectable to ends of a drawstring. Rotation of the drawstring hub in at least one direction is powered, such as by a force applied by flexed limbs. The crossbow further includes drawstring guides attached to the frame for guiding the drawstring across the projectile axis between the ends of the drawstring. The first and second drawstring guides each include a pulley wheel, wherein the drawstring is guided at least partially around each pulley wheel.
