Abstract: An oral cleaning system includes a toothbrush body with a first stem. The first stem has a rigid configuration and a first head with a first plurality of bristles. A channel is defined within the first stem and at least one fluid outlet is defined in the first head. The at least one fluid outlet is in fluid communication with the channel and is configured to facilitate irrigation of a mouth or teeth via the first head. A second stem is connected to the first stem and extends upwardly and outwardly from a distal portion of the first stem. The second stem includes a second plurality of bristles and is generally opposed and spaced from the first head. The second stem has a semi-flexible configuration such that the second head is resiliently movable inwardly or outwardly relative to the first head without substantially bending the first stem.

Abstract: Systems, methods, and other embodiments associated with bidirectional authorization are described herein. According to one embodiment, a method includes a user receiving a communication from an entity. In response to receiving the communication from the entity, the method further includes generating a token. The token may be personal identification number (PIN), alphanumeric value, code word, pass phrase, or security question. The token is received by a device of the user. Additionally, the token is transmitted to the entity. The user may then receive evidence of the token from the entity.

Abstract: The present invention provides compounds and methods of use thereof for treatment of certain disorders and conditions, for example brain injuries such as stroke or traumatic brain injuries.

Abstract: A printer includes a printhead assembly, a service station assembly, and a controller. The printhead assembly includes nozzles to eject fluid drops. The nozzles are divided into a least two groups with each group assigned a burst drop count, a post-burst delay, and a burst order. The service station assembly is to receive fluid ejected from the nozzles during spits. The controller is to control a spit of the printhead assembly by ejecting fluid from the nozzles of each group based on the burst drop count, the post-burst delay, and the burst order of each group until a target drop count for the spit is reached.

Abstract: An oral irrigator has a separate high pressure water system and low pressure mouth rinse system to deliver two different fluids to a pick or other accessories. The water system and mouth rinse system are combined in a handle. The pick is connected to the handle. The water system has a blocking valve located in the handle and the mouth rinse system has a hand pump located in the handle. The hand pump sits next to a valve button for closing the blocking valve. When the hand pump is pressed, it presses against the valve button of the blocking valve to shut off the source of high pressure water to the pick. The pressure in the pick drops so that the hand pump can then introduce mouth rinse into the pick. When the hand pump is released, the blocking valve opens up and high pressure water returns to the pick.

Abstract: A hockey training device is provided. The hockey training device provides a puck body connected to an elastic shock cord, the other end of which may attach to a user's hockey stick. The puck body has the dimensioning of a regulation hockey puck, while the shock cord is adaptable to different hockey sticks and skill levels of the individual user. The shock cord may be secured within a cavity of the puck body through a body hole thereof. The elasticity of the shock cord enables the user to repeatedly practice their passing skills as well as their receiving skills as the interconnected puck body elastically returns to the hockey stick during use.

Abstract: Systems, methods, and other embodiments associated with bidirectional authentication are described herein. According to one embodiment, a method includes a user receiving a communication from an entity. In response to receiving the communication from the entity, the method further includes generating a token. The token may be a one-time passcode, personal identification number (PIN), alphanumeric value, code word, pass phrase, or security question. The token is received by a device of the user. Additionally, the token is transmitted to the entity. The user may then receive evidence of the token from the entity.

Abstract: A printer includes a printhead assembly, a spit zone, and a controller. The printhead assembly includes nozzles to eject ink drops. The spit zone is to store maintenance ink. The controller is to move the printhead assembly over the spit zone while ink is ejected from the nozzles during spits.

Abstract: A system to provide additional functionality to robots in automated warehouse systems is disclosed. The system can include a number of additional components that can be attached to existing components of the warehouse system to improve safety, functionality, and decrease costs. The system can provide modular tools to enable robots to perform additional tasks without having equipment permanently installed on the robots. The bases or shelves for the automated warehouse system can be equipped with robotic arms, lights, cameras, sensors, actuators and other components to enable a robot to utilize a particular tool for a particular job. The robot and the bases or shelving units can also comprise complementary electronic connections to provide power and/or data communications between the robot, the bases or shelving units, and/or a management module.

Abstract: Techniques to facilitate collection of usage statistics of an application are disclosed herein. In at least one implementation, one or more visual elements of the application that respond to user inputs are determined. Frequency of use information for the one or more visual elements of the application is also determined. The frequency of use information for the one or more visual elements of the application is transferred to an application server, and the application server is configured to calculate usage statistics for the one or more visual elements of the application based on the frequency of use information.
