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.

Systems and methods are presented for establishing a communication link between two or more electronic devices. A portable eyewear electronic device is configured to communicate with a handheld electronic device, such as a ring, that in turn is retained by an accessory electronic device to establish a wired communication link. The accessory electronic device may be retained or housed by a second accessory electronic device, such as a remote control or wearable device.

An improved VR headset accessory, and in particular, a case for carrying the VR headset that has advanced functionality necessary for facilitating portable maintenance and usage. For example, the accessory houses additional batteries and/or power source connections for charging the VR headset as well as ancillary devices for controlling the display of content in the VR headset to create a controlled viewing environment. The accessory also houses a communication component for sharing content with a remote server.

A detachable electronic device and a dock thereof are provided. The detachable electronic device includes a first machine body, a second machine body, and a dock. The dock includes a pair of fixing brackets, a pair of rotating axles, a latch module disposed between the rotating axles, a lock base, and a linkage kit. The latch module can be arranged in a locked state or an unlocked state to lock or release the second machine body. The lock base is slidably disposed on one of the fixing brackets. The linkage kit has one end fixed to the latch module, and the other another end slidably sleeved onto the lock base. When an anti-theft lock is locked to the lock base, the lock base restricts a displacement of the linkage kit, and the linkage kit restricts the latch module to the locked state.

A security apparatus secures a laptop, and particularly a convertible laptop, to a mounting surface. The security apparatus comprises a housing assembly, and a first arm assembly and a second arm assembly extending from and retractable into the housing assembly. A first end assembly and second end assembly are mounted to the first arm assembly, and a second end assembly. Each arm assembly secures a first side and a second side of a lower body portion of the laptop. A trapping member is positioned in the housing assembly to lock the arm assemblies. A locking rod has a first end extending outside the support housing and a second end extending into the housing assembly and into engagement with the trapping member, the locking rod configured to move the trapping member into engagement with the first and second arm assemblies.

Disclosed is a system for associating a symptom with a medical condition. The system comprises a server arrangement, associated with a user device. The server arrangement is operable to: provide, to user device, a set of user activities; receive, from user device, information relating to selection of a user activity from set of user activities; receive, from user device, user input associated with selected user activity; analyse user input and assign performance score thereto; identify, based on performance score, one or more symptoms; and assign severity score to symptom for associating symptom with medical condition. Disclosed also is method for associating symptom with medical condition and computer program product to execute aforementioned method.

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.

An extensible display screen apparatus includes a power supply device and a screen display device. The screen display device includes at least one screen unit and a screen support assembly, wherein the at least one screen unit is disposed on the screen support assembly and the screen support assembly is arranged to support the at least one screen unit, whereas the at least one screen support assembly can electrically connect with the screen display device through the power supply device. The power supply device is configured to provide a working power to the at least one screen unit for a mobile electronic device to communicate with the at least one screen unit, wherein the said screen unit provides additional information of the mobile electronic device while being electrically connected with the screen display device.

A wireless communication system comprises a host device (110) and mobile devices (120) arranged for wireless communication and for distance (140) measurement. The host device has a user interface (113) comprising a connect button (115), and is arranged to execute a connection sequence upon a user activating the connect button. The connection sequence first determines respective distances between the host and respective mobile devices. A first mobile device is identified exhibiting a movement. Then a connection action is executed regarding a connection between the first mobile device and the host device. The mobile device is arranged for executing a ranging protocol and, upon subsequently receiving a connection message, executing a connection action regarding a connection between the first mobile device and the host device. Effectively a connection may be established upon the user of a mobile device pressing a single button on a selected host device and moving the mobile device.

A smartphone holding assembly includes a bowl that is positionable on a support surface. A sphere is rotatably disposed in the bowl and the sphere extends upwardly from the bowl. A mating unit is coupled to the sphere and the mating unit is matable to a personal electronic device. A pair of speakers is each of the speakers is positioned within the bowl to emit audible sounds received from the personal electronic device. A communication unit is integrated into the bowl to be wireles sly paired to the personal electronic device for streaming data from the personal electronic device.
