Abstract: A boat accessory system and method for attaching accessories to boats.

Abstract: The disclosure relates to a method including determining a treatment time of a dialysis treatment for a patient, receiving, from at least a sensor of a dialysis machine, a dialysate flow rate, the dialysate comprising bicarbonate pumped out of a bicarbonate source, wherein the bicarbonate source has an initial amount of bicarbonate, and predicting that by end of the dialysis treatment no more than a threshold amount of bicarbonate will be left in the bicarbonate source, and in response, determining that a clearance value during the treatment is or will be higher than the threshold clearance value, and sending, to a balancing system, an instruction to reduce the dialysate flow rate to a reduced rate, wherein the reduced rate results in reducing a rate of bicarbonate pumped out of the bicarbonate source while maintaining a clearance value of the treatment at no less than the threshold clearance value.

Abstract: The disclosure relates to a dialysis machine that comprises a dialyzer, a fluid source, a first line connected to the fluid source, and a container containing bicarbonate. The container connects to the first line and the fluid flows from the fluid source, through the first line, to the container. The dialysis machine further includes a second line connected to the container, a flow rate sensor connected to at least one of the lines, a pressure sensor configured for detecting fluid pressure of the container, a display, and a data processing apparatus. The data processing apparatus is configured to receive signals from the flow rate sensor and the pressure sensor. The data processing apparatus is configured to calculate a size of the container based on the received signals.

Abstract: A chair add-on, a chair, a chair modification, a chair hinge, and/or a hinge system that may be used to provide enhanced seating comfort to users. It is preferred, but not necessary, that the chair add-on, the chair, the chair modification, the chair hinge, and/or the hinge system is easy to use by users of all ages.

Abstract: An oyster opener device, system, kit, and/or method which preferably greatly enhances the ease and enjoyment of preparing oysters or other shellfish. The oyster opener may be entirely manually powered, manually powered and free of all motors and electrical components, may be operated by a powered device, may include a motor, or may be operated manually with a powered assist.

Abstract: A chair preferably configured for conversion between a preferred storage configuration and at least one preferred use configuration. When in one of the use configurations, the chair may have a recliner mechanism which allows the angle of the back support assembly relative to the seat frame to be progressively changed such that the back support assembly may be positioned at a reclined angular position. When in the preferred storage configuration, the back support assembly may be positioned at least partially within the seat frame to decrease the area of the footprint of the chair to facilitate storage of the chair.

Abstract: An adjustable frame configured to detachably connect to a backrest to allow the backrest to be transitioned between two or more angular positions relative to a horizontal plane, with at least one position being more upright and at least one position being more reclined. The adjustable frame may include a turret rotatably positioned on a base socket, the rotation of the turret from one position to another on the base socket causing the backrest to be held at a different angular position.

Abstract: A system and method for capturing images of an object upon which retroreflective materials have been applied, wherein at least some of the retroreflective materials appear to glow in the image or video being captured. An array of LEDs is provided that operates in different color frequency ranges. The color frequency ranges correspond to the reflectivity profile of the retroreflective materials that are applied to the object being imaged. The LEDs are attached to the camera, wherein the LEDs shine light in a same direction as the line of sight of the camera. The LEDs being activated during image capture can be varied. The light from the colored sets of LEDs causes retroreflective materials to appear. When recorded with the camera, the resulting images cause the retroreflective materials to glowing brightly in contrast to other objects in the captured image.
