a structure composed of three materials which are bonded together through the
use of adhesives such as epoxy.
Typically, sandwich structures utilize strong, thin materials as the
face sheets (top and bottom) layers, such as aluminum or composite
materials. They also use a weaker,
thick, light-weight core material such as a foam or honeycomb material. When these materials are bonded together, the
overall structure is extremely light-weight, and has superior stiffness
compared to regular materials, such as plastic or metal. Rather than synthetic and traditional core
materials (i.e. Rohacell™ foams and Nomex™ or Kevlar™ honeycombs), this
invention is a sandwich structure which uses natural cork agglomerate as a core
material. Natural cork agglomerate,
commonly known as corkboard, is the result of natural cork granules compressed
together. Our invention uses carbon
fiber-epoxy as the face sheet material, and is kept constant throughout all
experimentation to show that natural cork is a superior core material. Importantly, the face sheet material is not
limited to carbon fiber-epoxy.

A High-Fidelity Channel Simulator for Underwater Acoustic Communication

frequency acoustic communication (8-50 kHz), various physical processes,
including surface waves, subsurface bubbles, and ocean volume fluctuations, can
significantly affect the communication channel.
This invention is a high-fidelity communication channel simulator using
parabolic equation (PE) modeling of acoustic propagation and scattering, and a
linear surface model. The linear surface
model generates an evolving surface based on theoretical or experimental
directional surface spectrum and feeds the surface displacement and its
derivatives to the acoustic model. The
time-varying acoustic field is calculated using successive PE runs when the
surface evolves. Based on the surface
input and other environmental measurements, the channel simulator can generate
realistic time-varying impulse responses.
The output agrees well with the acoustic measurements in terms of arrival
time structure, intensity profile, and fluctuation characteristics.

Colectomy and Anastomosis Staple, Cut and Divide Device
Background

Background
Surgical
intervention is considered the treatment of choice for patients with colorectal
cancer in all stages, including stage IV, since in 25 to 40 percent of patients
the cancer is curative. However, colorectal cancers are often located in a
very difficult anatomic position in the pelvis, presenting surgeons with
strategically challenging approaches to their removal. Additionally, the current
instrumentation and technology has not evolved to the point whereby this
procedure can be performed completely laparoscopically. Current commercially available
instruments are cumbersome and tedious to work with.
Technology
A
novel, innovative surgical stapler that offers significant improvement in the
surgical approach to very difficult deep rectal cancers has been developed. This stapling device allows one to
ligate and divide the rectum distal to the lesion being removed, primarily
through an endorectal approach. Currently,
no commercially available device offers a comparable solution to this problem.
Inventor
Dr. Carman Giacomantonio
graduated from the Faculty of Medicine of Memorial University in 1991 and did
general surgical training at Dalhousie 1992-1997. He completed an MSc in
Pathology in 1998 and from 1997 to 1999 was training at the University of
Calgary in Surgical Oncology. He returned to Dalhousie in 1999 where he is
currently Assistant Professor of Surgery and a General Surgeon and Surgical
Oncologist at the Queen Elizabeth II Health Sciences Center. He is Head of the
Surgical Oncology Network for Cancer Care Nova Scotia. Dr. Giacomantonio has
won the Canadian Association of General Surgeons Resident Award for Teaching
Excellence, Excellence in Teaching Award of the Department of Surgery and the
Stevens Norvell Jr. Teaching Excellence Award.
Stage of Technology
The proprietary
technology is at the post concept and professional line drawing stage. Patent applications have been filed.
Opportunity
Dalhousie University
is seeking a development and/or licensing partner.
