Abstract: A laser device for providing light to a LiDAR system comprises a plurality of seed lasers configured to provide multiple seed light beams, at least two of the seed light beams having different wavelengths. An amplifier is optically coupled to the plurality of seed lasers to receive the multiple seed light beams. A power pump is configured to provide pump power to the amplifier, where the amplifier amplifies the multiple seed light beams using the pump power to obtain amplified light beams. A second light coupling unit is configured to demultiplex the amplified light beams to obtain a plurality of output light beams, at least two of the output light beams having wavelengths corresponding to the wavelengths of the at least two seed light beams.

Abstract: A smart current transformer for determining primary current or power consumption, by stepping down the primary current to a secondary current for subsequent measurement by a connected meter. The current transformer is provided with a connected non-volatile memory for storing calibration data (and optionally identification data) regarding that particular current transformer. The calibration data can include the gain error and/or phase delay for the current transformer, as determined from prior calibration testing of the current transformer. The calibration data may be communicated to or otherwise determined by the meter, and used to calibrate the measurement of the secondary current, in order to determine the primary current or power consumption. Also disclosed is a system and method utilizing such a smart current transformer.

Abstract: Embodiments of the present disclosure provide stray light filter structures in light detection and ranging (LiDAR) systems to attenuate stray light and reduce unwanted scattering. In some embodiments, a micro lens array is used together with a pinhole array to block stray light in the optical path just prior to the photodetector. In some embodiments, a bandpass optical filter is used in the optical path prior to the microlens array. In other embodiments, a slit filter is used further upstream in the optical path to block unwanted stray light and allow returning signal light to pass to imaging optics that provide a returning signal light image at a photodetector. In some embodiments, the imaging optics include a collimating lens and a focusing lens. In some embodiments, an optical bandpass filter is positioned on the optical path between the collimating lens and the focusing lens to reject light that is outside of a an expected wavelength range for returning signal light.

Abstract: The present invention provides a method and system for processing corporate action events by using at least one server to connect multiple overseas custodians and multiple domestic institution, wherein the at least one server classifies multiple corporate action events into multiple corporate action event modules, wherein each of the multiple corporate action event modules has multiple corporate action events each having corresponding multiple predetermined parameters, wherein the at least one server receives messages transmitted by a overseas custodians and determines if a message content contains parameters corresponding to the parameters of one corporate action event of one corporate action event module, so that the at least one server can automatically process the corporate action event and notify the result to a domestic institution corresponding to the corporate action event.

Abstract: A method for authenticating a user with service providers using a Universal OTP is provided, wherein a first request is received by a server from a first account on a mobile device of a user, wherein the first account is registered with said server; the first account is associated with a plurality of second accounts of service providers; the server transmits a Universal OTP to the mobile device, wherein the Universal OTP is not bound to any particular one of the plurality of second accounts; a terminal device of a first service provider inputs said Universal OTP and sends a second request to the server, wherein the second request comprises the Universal OTP and identification of the first service provider; and the server determines a corresponding second account of the first service provider according to the Universal OTP and identification of the first service provider so as to transmit information of the corresponding second account to the terminal device for authenticating the user.

Abstract: A system and method for automatically crossing platforms to perform shareholder voting, wherein a user's authentication information is acquired via a first platform to allow the user to perform stock transactions with a first brokerage firm, wherein a command of the first platform allows the mobile device of the user to a second platform on the mobile device, wherein the second server obtains identifying information of the authentication information of the user to identify the user and communicates with the second platform on the mobile device to enable the user to perform a first shareholder voting through the second platform based on the total number of the first stock of the user.
