  • Patent number: 10964582
    Abstract: An apparatus includes a transfer substrate with two or more transfer elements. Each of the transfer elements includes an adhesion element having a first surface adhesion at a first temperature and a second surface adhesion at a second temperature. The second surface adhesion less than the first surface adhesion. Each transfer element has a thermal element operable to change a temperature of the adhesion element in response to an input. A controller is coupled to provide the inputs to the thermal elements of the two or more transfer elements to cause a subset of the transfer elements to selectably hold objects to and release the objects from the transfer substrate in response to changes between the first and second surface adhesion of the subset of the transfer elements.

  • Patent number: 10220118
    Abstract: A self-replenishing biocompatible hydrogel having a zwitterionic polymer embedded throughout the matrix system to act as a lubricant and a surface modified with the same zwitterionic polymer. When surface material loss occurs in the hydrogel, such as a surface crack or a scratch, the damage propagates through the matrix rupturing the pockets of lubricant. The zwitterionic polymer is then drawn into the site due to the change in entropy at the surface and the positive and negative charge groups of the side chains fuse across the damage cite due to strong electrostatic attraction causing inter-chain association.

    Abstract: The invention provides for new viscoelastic silicone rubbers and compositions and methods for making and using them. The invention provides for viscoelastic silicone rubbers that are stiffer on short timescales than they are on long timescales. When subjected to brief stresses, they are relatively stiff and elastic, and they resist changing shapes. When subjected to sustain stresses, however, they are relatively soft and accommodating, and they gradually change shapes. When those stresses are removed, they gradually return to their original shapes. These viscoelastic silicone rubbers resist compression set and they are extremely resilient in response to sudden impacts. They can be dense rubbers, foam rubbers, and particles.

  • Patent number: 8742008
    Abstract: A process for forming a new group of siloxane-based compositions by a one-step co-hydrolysis and the compositions formed thereof. The siloxane-based compositions being functionalized with a carbon-carbon double (C?C) bond and a silicon-hydrogen (Si—H) bond. The C?C bond and hydrogen (H) each being attached directly to a silicon (Si) atom of the silicon-oxygen (Si—O) backbone of the siloxane-based composition. The C?C bond may be from a vinyl or an aromatic radical like a phenyl substituent. The C?C bond substituent provides the functionality needed for forming crosslinkages through standard dehydrocoupling catalysts without the need for siloxane fluids or organic compounds containing alkyl or aryl functional groups. The process provides for varying proportions of silanes as starting monomers to tailor the desired silicon, carbon, hydrogen and oxygen ratios in the siloxane-based compositions or resins.
