Patent number: 10003402Abstract: Challenges of direct-to-Earth (DTE) laser communications (lasercom) between spacecraft in low-Earth orbit (LEO) or medium-Earth orbit (MEO) and ground terminals can include short duration transmission windows, long time gaps between the transmission windows, deleterious effects of atmospheric turbulence, and the inability to operate in cloudy weather. Direct-link optical communications systems described herein can have data rates that are high enough to empty high-capacity on-board buffer(s) (e.g., having a capacity of at least about 1 Tb to hundreds of Tb) of a spacecraft in a single pass lasting only tens of seconds to a few minutes (e.g., 1-15 minutes), and overprovisioning the buffer capacity accounts for variations in the latency between links. One or more distributed networks of compact optical ground terminals, connected via terrestrial data networks, receive and demodulate WDM optical data transmissions from a plurality of orbiting spacecraft (e.g., satellites).Type: GrantFiled: January 8, 2016Date of Patent: June 19, 2018Assignee: Massachusetts Institute TechnologyInventors: Don M. Boroson, Bryan S. Robinson, Daniel V. Murphy, Jason Stewart, Farzana I. Khatri, Steven Constantine, David Jason Geisler, Timothy M. Yarnall, Zachary Darling

Patent number: 9998221Abstract: A satellite in low-Earth orbit (LEO) or medium-Earth orbit (MEO) with a modern image sensor and/or other remote sensing device can collect data at rates of 10 Mbps or higher. At these collection rates, the satellite can accumulate more data between its passes over a given ground station than it can transmit to the ground station in a single pass using radio-frequency (RF) communications. Put differently, the sensors fill the spacecraft's memory faster than the spacecraft can empty it. Fortunately, free-space optical communications signals can carry far more data than RF communications signals. In particular, a spacecraft can transmit over 1 Tb of data in a single pass using burst wavelength-division multiplexed (WDM) optical signals. Each burst may last seconds to minutes, and can include tens to hundreds of WDM channels, each of which is modulated at 10 Gbps or more.Type: GrantFiled: January 8, 2016Date of Patent: June 12, 2018Assignee: Massachusetts Institute of TechnologyInventors: Don M. Boroson, Bryan S. Robinson, Bryan M. Reid, Jamie W. Burnside, Farzana I. Khatri, Steven Constantine

Patent number: 8726527Abstract: A portable pencil sharpener is capable of being manually operable or operable to be driven by a remote torque driver. The pencil sharpener is capable of sharpening either a carpenter's pencil or a Number 2 pencil. Pencil shavings are retained in a compact housing and removed through a retractable panel.Type: GrantFiled: January 11, 2012Date of Patent: May 20, 2014Assignee: Acme United CorporationInventors: Richard Steven Constantine, Man For Ma

Patent number: 8689450Abstract: A knife comprising a housing and a rotating blade carriage pivotably associated with the housing. The knife further includes a compartment in which a plurality of blades can be stored and later advanced from the housing for performing a cutting action, the first end of the blade being exposed. The rotating blade carriage can be rotated with respect to the housing and placed in a second position so that the opposite end of the same blade is exposed for performing a cutting action when advanced. The rotating blade carriage can be selectively locked in the first or second position. A carriage locking lever can be accessible for unlocking the rotating blade carriage for blade reversal. When removal of the used or worn blade is desired, the knife can have one or more blade release members that allow the disengagement of the blade from the knife so that the user can manually remove the blade without the requirement of disassembly or partial disassembly of the knife.Type: GrantFiled: April 29, 2011Date of Patent: April 8, 2014Assignee: Acme United CorporationInventors: Richard Steven Constantine, Man For Ma, Anthony Sgroi, Jr.

Patent number: 8677630Abstract: A utility knife has a receiving cavity which opens through the body. A cartridge comprising a magazine of blades is removably insertable into the receiving cavity. A carrier within the body is manually operable for receiving a blade from the cartridge and positioning the blade for extension through the opening to present a cutting edge. The cartridge may be released from the utility knife body by depressing a button and withdrawing the cartridge. The cartridge is releasably held in place within the knife body and releasable when the blade carrier is in its retracted position and the release button is depressed. When the thumb button moves the blade carrier into its extended position to expose the knife blade, the cartridge is rendered unreleaseable even if the release button is depressed.Type: GrantFiled: January 20, 2011Date of Patent: March 25, 2014Assignee: Acme United CorporationInventors: Richard Steven Constantine, Michael E. Peterson, Javier Verdura, Jonathan A. Lee, Cody Man For Ma
