Patent number: 9355813Abstract: A method and system is provided for automatically preparing transmission electron microscopy (TEM) samples for examination by depositing extremely small samples onto a grid without need for a blotting step. A sample liquid droplet is formed at the end of a capillary, wherein a portion of the liquid is transferred to the TEM sample grid by contact. The excess volume in the liquid droplet is then retracted by an adjacent capillary. After a predetermined time interval, the retraction capillary is moved toward the drop of the sample to remove the excess volume. As compared to a conventional machine, where the blotting procedure can deform the structure of the molecule of interest, the present invention utilizes a very low shear rate for removal of the excess sample fluid.Type: GrantFiled: April 4, 2012Date of Patent: May 31, 2016Assignees: BROWN UNIVERSITY, RHODE ISLAND BOAD OF EDUCATION, STATE OF RHODE ISLAND AND PROVIDENCE PLANTATIONSInventors: Arijit Bose, Anubhav Tripathi, Jinkee Lee

Patent number: 9345432Abstract: A method and an apparatus are disclosed for extending the service life of a battery source by fully utilizing the energy in batteries and/or providing higher energy reserve using multiple batteries. An universal battery bank consists of an ensemble of possibly heterogenous batteries all connected in series to provide a usable operational energy source. For a universal battery bank consists on N batteries, the minimum operational voltage for the individual batteries (Vmin) can be lowered to Vmin/N on average, thereby extending the time interval between battery replacements and draining the individual batteries more efficiently. To exploit this power supply that may vary over a wide voltage range, electronics are designed to monitor the individual batteries, guard against excessive voltage and current, and provide constant current sources and/or constant voltage sources for various appliances.Type: GrantFiled: June 19, 2012Date of Patent: May 24, 2016Assignee: Rhode Island Board of Education, State of Rhode Island and Providence PlantationsInventors: John Salisbury, Ying Sun
