A medical fluid pump of the infusion or syringe pump design includes a fluid pump housing which includes a display unit, in particular a display or touch display, with a plurality of display panels that are prepared and configured to display at least one respective function parameter of the fluid pump, including at least one setting parameter which can be set directly by a user of the fluid pump and a plurality of operating parameters which cannot be set directly by the user. The representation of the at least one setting parameter stands out visually against the operating parameters, such as by displaying the at least one setting parameter in an enlarged size compared to the operating parameters.

Electromechanical polymer (EMP) actuators are used to create haptic effects on a user interface deface, such as a keyboard. The keys of the keyboard may be embossed in a top layer to provide better key definition and to house the EMP actuator. Specifically, an EMP actuator is housed inside an embossed graphic layer that covers a key of the keyboard. Such a keyboard has a significant user interface value. For example, the embossed key provides the tactile effect of the presence of a key with edges, while allowing for the localized control of haptic vibrations. For such applications, an EMP transducer provides high strains, vibrations or both under control of an electric field. Furthermore, the EMP transducer can generate strong vibrations. When the frequency of the vibrations falls within the acoustic range, the EMP transducer can generate audible sound, thereby functioning as an audio speaker.

A powered communication system comprises an improved layout of keys configured to treat, mitigate, or delay the onset and reduce the severity of symptoms of carpal tunnel syndrome (CTS) and other pathologies by reducing movement of a user's fingers during typing. A layout of the powered communication system comprises the most-used letters on a home or center row while retaining a plurality of keys in the same placement as the QWERTY keyboard. The powered communication system further comprises customizable function keys to further reduce finger movement and at least one sensor to monitor a user's health while typing.

A piezo haptic keyboard and touchpad user identification system may comprise a processor receiving an authenticating user input identifying an authorized user of the information handling system, and a controller operably connected to a plurality of piezo electric elements situated beneath the keyboard. The controller may detect haptic hardware typing or touch behavior parameters describing characteristics of a plurality of deformations of the piezo electric elements during interaction between the authorized user and the keyboard, and the processor may use machine learning to identify a repeated pattern of values for a combination of the haptic hardware typing or touch behavior parameters reoccurring during interaction between the authorized user and keyboard. The processor may associate the repeated pattern of values for the combination of the haptic hardware typing or touch behavior parameters with the authorized user for later, passive authentication of a user based on typing dynamics.

A dynamic texture device coupled to an information handling system input/output device adjusts texture at the input/output device surface based upon texture information generated at the information handling system, such as a walking surface in a virtual world defined by a gaming application. Texture at an elastic cover is adjusted by applying variable magnetic fields to a magnetorheological fluid (MRF) disposed under the elastic cover in a reservoir. For example, an electromagnet changes pole orientation and magnetic strength at MRF contained in a reservoir under a keyboard palm rest to simulate walking in a virtual world on different types of surfaces.

The first single key light guide area has a first through hole accommodating the first light source assembly. The second single key light guide area has a second through hole accommodating the second light source assembly. The connection area is located between the first and second single key light guide areas and has an accommodating hole. The flexible circuit board is overlapped with the light guide plate with the positioning member being accommodated in the accommodating hole.

This application discloses a wireless keyboard. The wireless keyboard includes a connection portion. The connection portion includes an accommodating cavity with an opening at an end and used for accommodating an electronic stylus. A wireless charging coil is arranged in the accommodating cavity. A charging interface and a wireless charging control module are arranged in the wireless keyboard. The wireless charging control module is connected to the charging interface and the wireless charging coil. The charging interface can receive a direct current signal. The wireless charging control module can convert, if it is detected that a direct current signal is inputted to the charging interface, the direct current signal into an alternating current signal and transmit the alternating current signal to the wireless charging coil. The wireless charging coil generates an alternating electromagnetic field in response to the alternating current signal, to wirelessly charge the electronic stylus.
