The current invention concerns a head-mounted display apparatus, preferably smart glasses, with autofocus system, whereby the alignment of lens assembly and light beam emitter is improved.

Head-mounted display apparatus with autofocus system

The present invention relates to a bridge device operable between a master device and a slave device of a communication system, said master device and said slave device arranged for communicating with each other via a parent IC bus and a child IC bus and using the IC protocol, said bridge device comprising—a parent module arranged for connecting said parent IC bus and comprising a parent IC transmitter/receiver device and a parent module state machine, —a child module arranged for connecting said child IC bus and comprising a child IC transmitter/receiver device and a child module state machine, whereby said parent module and said child module each comprise an internal bridge interface to exchange messages between said parent module and said child module, said messages being generated by said parent module state machine or said child module state machine in response to a change of state caused by an event on their respective IC buses, whereby said parent module and said child module are each arranged for translating an IC event to a message and for forwarding said message to the module at the other side of the bridge device via said internal bridge interfaces, said module at the other side being arranged for further transmitting said message as an IC event towards the IC bus at the other side of the bridge device, and whereby said parent module and said child module are further each arranged for holding the communication towards the respective IC bus by stretching a clock line on their respective IC bus until a message, based on an event occurring on the IC bus at the other side of the bridge device and instructing continuation of the communication, is received via said internal bridge interfaces from the module at the other side of the bridge device.

The present invention relates to a method for performing wake-up signalling between a host device and a client device of a communication system, said host and said client device being in a two-wire connection () with each other and at least one of said host and said client device being in an idle state, said host and said client device each comprising a data controller () arranged for data communication control and a power state controller () arranged to switch the device between at least an active state and said idle state, whereby the data controller of said at least one of said host and client device is disabled during the idle state. The method comprises&#x2014;generating in the power state controller of said host or client device a wake-up signal and transmitting said wake-up signal via said two-wire connection to the other device, said other device being in said idle state,&#x2014;detecting said wake-up signal with said power state controller () of said other device and, upon said detecting, setting a control signal to transition said other device out of said idle state.

The present invention relates to a system comprising glasses (), a communication unit () and a cable (), whereby the cable comprises two galvanic connections adapted for transporting power and bidirectional data traffic, whereby the glasses and the communication unit are arranged for multiplexing a plurality of outgoing data streams into a multiplexed data stream to be transmitted over said cable and arranged for receiving an incoming data stream and demultiplexing said incoming data stream into separate data streams, and whereby said communication unit () is arranged for being connected wired or wirelessly to an external processing device (), preferably the external processing device being a smartphone.

System comprising glasses and a communication unit

The invention relates to a method for providing distance information of a scene with a time-of-flight camera, comprising the steps of emitting a modulated light pulse towards the scene, receiving reflections of the modulated light pulse from the scene, evaluating a time-of-flight information for the received reflections of the modulated light pulse, and deriving distance information from the time-of-flight information for the received reflections, whereby a spread spectrum signal is applied to a base frequency of the modulation of the light pulse, and the time-of-flight information is evaluated under consideration of the a spread spectrum signal applied to the base frequency of the modulation of the light pulse. The invention further relates to a time-of-flight camera for providing distance information from a scene, whereby the time-of-flight camera performs the above method.

Method and time-of-flight camera for providing distance information

An electronic driver circuit for LEDs and LASERs is provided for use in time-of-flight applications featuring a high efficiency of energy-conversion and a high precision of distance-measurements based on a dual conversion circuit. A voltage to voltage DC-DC conversion is hereby merged with a DC-voltage to pulsed-current booster, this booster operating at a time-of-flight modulation frequency. At the start of a new measurement cycle, the PWM signal for driving the DC-DC conversion is updated in response to currents observed during previous illumination periods.
