  • Patent number: 11967657
    Abstract: Approaches for the foil-based metallization of solar cells and the resulting solar cells are described. In an example, a solar cell includes a substrate. A plurality of alternating N-type and P-type semiconductor regions is disposed in or above the substrate. A conductive contact structure is disposed above the plurality of alternating N-type and P-type semiconductor regions. The conductive contact structure includes a plurality of metal seed material regions providing a metal seed material region disposed on each of the alternating N-type and P-type semiconductor regions. A metal foil is disposed on the plurality of metal seed material regions, the metal foil having anodized portions isolating metal regions of the metal foil corresponding to the alternating N-type and P-type semiconductor regions.

  • Publication number: 20240088317
    Abstract: Approaches for fabricating one-dimensional metallization for solar cells, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a back surface and an opposing light-receiving surface. A plurality of alternating N-type and P-type semiconductor regions is disposed in or above the back surface of the substrate and parallel along a first direction to form a one-dimensional layout of emitter regions for the solar cell. A conductive contact structure is disposed on the plurality of alternating N-type and P-type semiconductor regions. The conductive contact structure includes a plurality of metal lines corresponding to the plurality of alternating N-type and P-type semiconductor regions. The plurality of metal lines is parallel along the first direction to form a one-dimensional layout of a metallization layer for the solar cell.

  • Patent number: 11923474
    Abstract: A solar cell can include a conductive foil having a first portion with a first yield strength coupled to a semiconductor region of the solar cell. The solar cell can be interconnected with another solar cell via an interconnect structure that includes a second portion of the conductive foil, with the interconnect structure having a second yield strength greater than the first yield strength.

  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Publication number: 20230192601
    Abstract: The present disclosure provides processes and apparatuses for the scaled-up manufacture of lomustine via continuous flow manufacture. Such continuous flow processes may optionally include the crystallization of lomustine and the apparatuses may optionally include crystallization apparatuses/reactors in either batch or continuous flow design. In one aspect of the disclosure, a process for making lomustine is provided comprising treating solutions of 2-chloroethylisocyanate with a solution of cyclohexylamine with continuous-flow pumps in a gram-flow reactor to form a combined solution, adding deionized water with a continuous flow-pump to the combined solution to form a liquid-organic phase solution, extracting the organic phase from the solution and treating with a solution of t-butyl nitrite with a continuous flow pump in a gram flow reactor to form lomustine.

  • Publication number: 20230183246
    Abstract: The present disclosure relates to a telescoped continuous flow Sonogashira coupling synthesis for some lead compounds to support in vivo studies and pre-clinical evaluation. The application of high throughput tools combined with the telescoped continuous synthesis method can enable an efficient and safe synthesis of compounds of interest involving hazardous coupling reagents such as HATU, while minimizing by-product formation.

  • Publication number: 20210054048
    Abstract: Disclosed herein is an optimized Elastin-like peptide purification scheme from whole cell lysate that is broadly applicable to neutral, acidic or basic ELP polypeptide. The method involves the use of one or more organic solvent to extract the ELP polypeptide from whole lysate followed by optional back extraction, precipitation, hot spins, and/or dialysis to purify the target ELP polypeptide.

  • Publication number: 20210023872
    Abstract: A plurality of modular tiles can be connected to form a writing surface. The modular tiles are shaped to enable multiple tiles to be connected to form a continuous surface (e.g., hexagonal, rectangular, etc.). Each modular tile has a writing element and a friction element opposite the writing surface to prevent the modular tile form slipping when placed on a horizontal surface. The modular tiles may also have a coupling mechanism, such as magnets with appropriate polarization, allowing the modular tiles to be coupled to one another to form a large surface and then be detached for simpler storage of the modular tiles. The modular tiles may further include lights, displays, or additional electronics to allow a connected computing device to display on the writing surface.

  • Patent number: 8074479
    Abstract: An electromechanical locking system (8) comprises a lock (12) and a key (14). The lock includes a cylinder (16), an electronic control unit (18) which is housed within the cylinder, a tailpiece (20), and an electrically-operable clutch mechanism (22) which is housed within the cylinder (16). The cylinder (16) is rotatably mounted to a first component to be locked and the tailpiece includes an adapter (24) which is operable to interfere with the movement of a second component to be locked to the first component. The control unit (18) draws power from the key and is operable to generate an actuation signal for actuating the clutch mechanism (22) which releasably connects the cylinder and the tailpiece when actuated, thereby causing them to become rotatably coupled.
