  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Patent number: 5797078
    Abstract: An apparatus for cleaning a charge retentive surface of a photoreceptor which includes a rotating brush for cleaning the charge retentive surface of a photoreceptor. A spring or other device is used to maintain constant, uniformly distributed contact between the charge retentive surface and the rotating cleaning member together. The use of one or more pressure rollers to maintain the cleaning brush next to the photoreceptor belt can prevent undesirable friction, heat and/or static charge buildup adjacent to the photoreceptor, and can prevent photoreceptor jamming and other malfunctions. The resulting self regulating cleaning brush contact improves photoreceptor cleaning effectiveness despite brush aging, bristle wear or set, or other factors effecting the radius of the cleaning brush or its relative positioning in the photoreceptor cleaning assembly. The present invention results in the uniform distribution of the contact pressure on the photoreceptor, which may monitored and/or be controlled.

  • Patent number: 5175591
    Abstract: Apparatus for cleaning residual toner from a charge retentive surface is provided with a rotating abrading brush, located upstream of a primary cleaner relative to a feeding direction of the charge retentive surface. The abrading brush contacts and abrades the charge retentive surface. The abrasion of the charge retentive surface reduces the friction between the charge retentive surface and a primary cleaner (which is preferably a cleaning blade biased against the charge retentive surface) and prevents the formation of comets (adhered toner particles) on the charge retentive surface.
