To couple light between an optical fiber and a grating coupler of a photonic integrated circuits, a mirror is provided to turn light to/from the optical fiber to allow the axis of the optical fiber to be oriented at small angles or parallel to the surface of the PIC, and lowered close to the surface of the PIC. The mirror is further configured to reshape light from a flat polished optical fiber to produce a mode field resembling the mode field of an angled polished optical fiber, to match the design angle of existing grating couplers that are designed to work with angled polished optical fibers. The mirror and optical fiber alignment structure in the optical connector are integrally/simultaneous formed by precision stamping.

The die includes a plurality of contact pads, a first signal line coupled to the plurality of second contacts and to a first one of the plurality of contact pads, and a plurality of second signal lines, each second signal line being coupled to one of the plurality of first contacts, groups of the second signal lines being coupled together to drive a group of the plurality of heaters with a single signal, each group of the second signal lines being coupled to a remaining one of the plurality of contact pads.

An optical coupling device for routing optical signals for use in an optical communications module, in which defined on a base are a structured surface having a surface profile that reshapes and/or reflect an incident light, and an alignment structure defined on the base, configured with a surface feature to facilitate positioning an optical component on the base in optical alignment with the structured surface to allow light to be transmitted along a defined path between the structured surface and the optical component. The structured surface and the alignment structure are integrally defined on the base by stamping a malleable material of the base. The alignment structure facilitates passive alignment of the optical component on the base in optical alignment with the structured surface to allow light to be transmitted along a defined path between the structured surface and the optical component. The structured surface has a reflective surface profile, which reflects and/or reshape incident light.

An interchangeable adapter and head piece for changing a light bulb that includes a head piece that has a base plate with a primary gripping member and a secondary gripping member for engaging the light from the platform of the first side of the base plate away from the second side.

A data center includes various sets of infrastructure modules which each provide a particular type of infrastructure support to support computing operations in the data center. Separate sets of infrastructure modules can be installed incrementally based on incrementally changing support capacity for the corresponding type of infrastructure support in the data center. Such incrementally changing support capacity can be based upon support requirements of electrical loads, including rack computer systems, which are inbound to the data center. Where support capacity for a particular type of infrastructure support drops below a threshold, a quantity of additional infrastructure modules which provide the particular type of infrastructure support can be selected and installed to increase the support capacity. Separate sets of infrastructure modules can be selected and installed independently of each other, to independently adjust support capacity for separate types of infrastructure support, which can minimize excess support capacity at any given time.

A twist-and-lock mounting bracket may secure a lighting fixture to a mounting surface. The twist-and-lock mounting bracket may define an aperture having features corresponding to the shape of a twist-and-lock element disposed on a housing of a lighting fixture. Accordingly, the twist-and-lock element may be configured to extend through the aperture while the corresponding features of the twist-and-lock element and the aperture are aligned. The housing may then be rotated such that the tabs do not align with the corresponding features of the aperture, and the twist-and-lock element is thereby prevented from sliding through the aperture. The mounting bracket may be secured to a junction box positioned within a mounting surface, or it may be secured to a biasing bracket having one or more second resilient members configured to engage the interior of a recessed can light, such that the lighting fixture may be secured to the recessed can light.

An interchangeable adapter for changing a light bulb that includes a head piece that has a base plate with opposite first and second sides and that defines a platform at the first side. A primary gripping member extends from the platform of the first side of the base plate away from the second side. The primary gripping member is positioned substantially centrally with respect to the platform to engage the light bulb. A secondary gripping member extends from the platform of the first side of the base plate away from the second side. The secondary gripping member surrounds the primary gripping member and is configured to grip the light bulb. An engagement member extends from the second side of the base plate away from the first side for engaging a holder of the adapter.
