Abstract: A variator includes an epicyclic gear set that has at least three nodes. The variator includes a pumping unit connected to a first node of the epicyclic gear set. The variator includes a clutch connected to a second node of the epicyclic gear set. The clutch is selectively movable between three positions. When in the first position, the clutch allows the second node to freewheel. When in the second position, the clutch connects the second node to a fixed surface. When in the third position, the clutch connects the second node to an electric motor. The variator includes a receiver connected to the third node of the epicyclical gear set. The receiver is configured to receive a drive shaft.

Abstract: Methods and systems for the secure delivery and processing of exam questions and responses. One or more exam questions and one or more identifiers of one or more designated individuals who are authorized to print the one or more exam questions are transported using a secure protocol. Biometric information is obtained from an individual requesting to print the one or more exam questions and information is read from an embedded tag that identifies a corresponding exam sheet as a unique exam sheet for a specified exam and that identifies that the specified exam is for a particular student. The specified exam is printed on the unique exam sheet in response to a first current time being in a printing time window TW1 and the biometric information from the individual matching biometric information of one of the one or more designated individuals.

Abstract: A flow of air is directed at the face and into the nose and mouth so as to decrease taste and inhibit appetite.

Abstract: A plurality of scents that produce a particular effect on an individual's appetite are identified. The plurality of scents are delivered to produce the particular effect on the individual's appetite. The particular effect may include one of suppression of the individual's appetite and enhancement of the individual's appetite. Identifying a plurality of scents that produce a particular effect on an individual's appetite may include delivering a second plurality of scents to the individual, detecting a response of the individual to each respective one of the second plurality of scents, and identifying the plurality of scents that produce the particular effect on the individual's appetite based on the responses detected. A schedule for delivery of scents may be generated based on data relating to the individual's responses, and the plurality of scents may be delivered in accordance with the schedule.

Abstract: A controller configured to provision on a surface of an environment includes a projector configured to project light for a user interface through an opening in the surface, wherein the projector is located on a first side of the surface. The controller includes a waveguide located within the opening of the surface, wherein the waveguide is configured to transmit the light from the projector through the opening in the surface. The controller further includes a direction element located on a second side of the surface, wherein the direction element is configured to direct the light from the projector to a user.

Abstract: The scent delivery device employs a housing and scent generator which selectively releases scent. The housing is mounted on a counter and allows a user to selectively sample a variety of scent. The scent travels to the user's nose by diffusion.

Abstract: A personal, portable scent delivery device including a portable housing which is either a housing adapted to be worn by a user in close proximity to a nose of a user, or is a portable electronic device which is used by the user in close proximity to the nose of the user; and a means for selectively generating scent housed in said housing, wherein said scent travels by diffusion to the nose of the user.

Abstract: The communication privacy mask has a housing having an opening coupled with a mouth piece and a hollow sound tube mounted in the housing. A microphone is positioned in the sound tube with a space in front of the front end of the microphone.

Abstract: The portable scent delivery device employs a housing and scent generator which selectively releases scent. The housing is suitably a headset, hat, shoulder harness or personal electronic device like a mobile telephone. The scent travels to the user's nose by diffusion.

Abstract: A machine can be accessed and controlled with the help of an interface device. The customizable interface device contains device elements that define features relating to the external representation and internal functionality of the interface device, as linked to one or more machines. An operator can use a configuration station to implement single or reoccurring queries that interact with the interface device and corresponding machines. In particular, the queries target the configuration of device elements in the interface device. The process can include temporarily unloading unused features from active memory and mirroring property changes initialized by a source. An emulator can assist in the configuration process by providing a preliminary software representation of the interface device hardware. A user can develop, test, and reconfigure functions on the emulator before loading the finalized platform to the interface device.
