A method for proximity detection and ranging with neighboring devices is described here. The method includes identifying, by a processor of a first tag, a second tag from a group of tags within a predefined range of the first tag. The method further comprises initiating, by the processor, transmission of a packet to the second tag in the group of tags identified within the predefined range. The method further comprises, in response to the transmission of the packet, receiving, by the processor, a response packet from the second tag. The method includes in response to receiving the response packet, determining a tag distance between the first tag and second tag. The method includes determining that the tag distance associated with the second tag is less than a predefined distance, generating, by the processor, an alarm or notification to the first tag indicating that the predefined distance is crossed.

A method of automatically triggering scanning operation through specific motion includes steps as follows. A specific motion trajectory of a scanning device is sensed to determine whether the scanning device is moved along a predetermined path. If so, an image sensor of the scanning device is switched on. A determination is made as to whether the scanning device is moved down to a lower position. If so, the image sensor of the scanning device is switched off.

A wearable device enables a user to switch the device to another state while the user is pointing a finger at an object at a distant position. A wearable camera that a user wears on a finger includes a release switch configured to switch to another state in response to an operation of the user, who is pointing an index finger at an object, with a thumb that is different from the index finger. Such switching of the release with the thumb enables the user to shoot an image of an object at a distant position.

The present invention relates to a technical field of the code scanning device, and in particular, to a handback-type code scanning terminal. The present invention discloses a handback-type code scanning terminal including a terminal body and a fixing member, the fixing member is used to fix the terminal body on a handback, a code scanning device and a gesture sensing device for triggering an on/off code scanning function of the code scanning device are disposed on the terminal body, the gesture sensing device is used to sense a lifting action of a thumb, and the thumb is a thumb of a hand for fixing the terminal body. The present invention does not have to use hands of an operator, and can release both hands of the operator to perform normal manual tasks, a code scanning operation is convenient, a working efficiency is improved, and a user experience is greatly improved.

An ambidextrous hand mount for an electronic device comprises: a proximal fastener configured to engage with a wrist of an operator; a distal fastener configured to engage with a finger of the operator; a body connecting the proximal fastener and the distal fastener and configured to extend along a back of a hand of the operator from the wrist to the finger; wherein the body includes: a main segment configured to support the electronic device; and a flexible segment between the main segment and the proximal fastener, the flexible segment configured to deform to accommodate changes in an angle between the body and the proximal fastener.

The present disclosure provides an attachment device comprising a first subassembly, comprising a mounting component, a retainer component, coupled to a second subassembly comprising a first rotatable component, a second rotatable component, and a trigger assembly. The mounting component comprises an opening defining at least one slot. The retainer component is coupled to the mounting component defining a first cavity. The spring component, housed in the first cavity, is coupled to the retainer component. The first rotatable component is coupled to the second rotatable component to define a second cavity extending from a first surface of the first rotatable component to a second surface of the second rotatable component. A trigger actuator of the trigger assembly is housed in the second cavity. The first rotatable component defines at least one tab defined to be received within the at least one slot of the mounting component.

A wrist-worn device comprises a band or strap for attaching the device to a wearer's wrist; a product code reader comprising at least one optical component; a sensor; and a processor. The sensor is configured in use to detect rotation of the device indicative of a rotation of the device around a longitudinal axis of the wearer's wrist. The processor is coupled to the sensor and to the product code reader and is configured in use to activate the optical component, or place the device in a state in which a predefined subsequent action or actions can activate the optical component, when the sensor detects a rotation of the device over at least a predefined angle.

Systems and methods involving one or more wearable components that obtain information about a surrounding environment and provide information to a user to assist user in retrieving objects from the surrounding environment. The information may include navigation information related to a route that the user may take to retrieve an object, as well as information about the object to be retrieved. The wearable components may be include ones that may be mounted on the head of the user, as well as components that the user may wear on other parts of the body or that attach to clothing The wearable components may include image sensors, microphones, machine-readable symbol readers, range-finders, accelerometers, and/or gyroscopes that may collect information from and about the surroundings of the user. The wearable components may also include one or more of a set of speakers and/or a display subsystem to provide information to the user.
