Abstract: A micro optical engine assembly including a printed circuit board, a frame mounted on the printed circuit board, a micro optical engine mounted on the printed circuit board within a central space of the frame, a jumper having a lens-carrying end placed on top of the micro optical engine and aligned therewith by alignment members to thereby limit horizontal movement of the jumper, and a latch having a snap mechanism releasably snapped onto the frame, and at least one spring plate resiliently pressing against an upper surface of the jumper when the latch is snapped onto the frame to thereby limit vertical movement of the jumper.

Abstract: A CWDM transceiver module includes: a substrate; a plurality of light sources disposed on the substrate; a spacer layer disposed above the substrate, a cavity being defined in the space layer to accommodate the light sources; a cap layer transparent to light emitted from the light sources and disposed on the spacer layer, a notch for assembling a waveguide being formed in the cap layer; a plurality of lenses disposed on the cap layer facing the light sources; reflector coating and filter coating disposed on surfaces of the cap layer; an active alignment element disposed on the cap layer; and a reflector disposed at bottom of the notch.

Abstract: An armband includes an electronic device holder including an outer shell for holding an electronic device. A first wing structure with a first strap opening extends outward from the outer shell and a second wing structure with a second strap opening extends outward from the outer shell. The armband further includes a strap with at least one attachment portion located between a first end portion and a second end portion of the strap for detachably securing the first end portion after the strap has passed through the first strap opening and for detachably securing the second end portion after the strap has passed through the second strap opening. An inner layer of the strap includes a moisture wicking material.

Abstract: A system and method is provided to track users across applications and devices, and to distinguish similar or different users among a number of commonly-used devices. Accordingly, systems and methods are provided for analyzing user device information to determine different users among a number of devices. In particular, user's behavior when using the devices is observed, and responsive to that observed behavior, is the determined whether a particular users are distinguishable from other users. For instance, it may be useful to distinguish between users that operate the same devices or exist within a similar network (e.g., a home network, a workplace network, etc.) for various purposes. For instance, it may be useful to distinguish between users for displaying advertising to these users, performing some other operation with respect to a subset of the users.

Abstract: A weatherproof phone case including a bottom portion having side walls defining a closed perimeter, the side walls having an outer surface with at least two channels and an inner surface having a flange. The phone case also including a rigid back plate defining a perimeter and having at least two protrusions that travel around at least a portion of the perimeter, the at least two protrusions connectable to the at least two channels, the back plate and the side walls forming a cavity for the placement of a mobile device. The phone case also including a top portion having an outer perimeter, a top surface, an extruding wall extending therefrom and an opening positioned between the top surface and the extruding wall, the top portion configured to fit onto the bottom portion such that the opening receives the flange of the bottom portion. The phone case also including a transparent screen attached to the outer perimeter to allow viewing into the cavity.
