Abstract: A vessel for containing, cultivating and suspending plants. The vessel consolidates and reduces the time necessary for the process of sowing seeds, transplanting plants, growing plants, recycling plant materials, dismantling and storage, by simplifying and reducing the number of process steps.

Abstract: An autonomous light tracking device includes first and second movable light-sensitive sensors that produce respective first and second electrical signals representative of light received from a remote light source, and a first comparator that receives the first and second electrical signals and is adapted to provide a first output signal when the first electrical signal differs substantially from the second electrical signal in a predetermined manner. The autonomous light tracking device also includes a motor coupled to the first and second movable light-sensitive sensors, that selectively moves the first and second movable light-sensitive sensors in response to the first output signal so as to maintain the first and second movable light-sensitive sensors in approximate relative alignment with the remote light source over a substantial arcuate range of motion, and a power supply for the first comparator and the motor, that generates required electrical power from the remote light source.

Abstract: A medical instrument comprising a Veress needle, a dilating obturator, and a cannula. The Veress needle has a tubular safety obturator with an opening in its front section at a needle tip of the Veress needle. A guide with a guide slot can be positioned in a patient's vagina against the posterior fornix of the vagina to guide the Veress needle through the vaginal and peritoneal walls. A guide wire may be passed through the Veress needle and through the hole in the peritoneum wall formed by the Veress needle to guide the dilating obturator through the hole.
