    CPC classification number: G02C7/101

    Abstract: Eyewear exhibiting a variable light transmittance functionality is achieved by including a smart lens incorporating an electrochromic (EC) polymer, switchable between a first state and a second state in response to a voltage selectively applied thereto. The smart eyewear includes the smart lens, a voltage source, and a support. The EC polymer transmits more light in the first state than in the second state, because changing the state of the EC polymer varies the light transmittance of the smart lens. The voltage source is configured to provide the voltage required to switch the EC polymer between the first state and the second state, while the support member is configured to support the smart lens and enable a user to wear the smart eyewear. Embodiments can include sensors and controllers to automate the switching, as well as energy harvesting elements to increase battery life.

    Abstract: The present disclosure discloses an index constructing method, search method, device and system. The index constructing method includes: constructing data obtained in each preset time period into a primary index segment, respectively, and merging the constructed primary index segments into a primary index segment set after each preset time period is over; copying and merging each primary index segment in the primary index segment set into a corresponding large index segment, to obtain a large index segment set; and sending the primary index segments in the primary index segment set or the large index segments in the large index segment set to a search device to provide a search service. The present disclosure constructs the primary index segments on the basis of time, merges the constructed primary index segments into the large index segment, and provides the search service simultaneously with the primary index segments or the large index segments, thus, improving search speed.

    Abstract: This invention relates to a method and system for digitizing bit synchronization in wireless communication. The method comprises delaying at intervals an input signal sequence, which contains at least one path of input signals; multiplying each path of input signals respectively by input signals in at least one local channel within one symbol period, the results are accumulated and then averaged within the symbol period; comparing absolute values of the averaged values of each channel of each path of input signals, and choosing a maximum absolute value to output as a bit synchronization extremum of the path; comparing the bit synchronization extremums of each path of input signals, and choosing a path of input signals having a maximum extremum as a decoded data output. This invention utilizes DMR bit synchronization technology that facilitates digitalization and reduces calculation, thereby greatly increase data rate, save resources and reduce costs.
