3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency
Advanced Materials Technologies, EarlyView.A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.

Advanced Materials Technologies, EarlyView.A flexible pressure sensor utilizing a 3D dual‐pore polyurethane structure is developed to overcome the intrinsic trade‐off between sensitivity and linearity. By inducing sequential buckling through distinct pore sizes and shapes, the device achieves highly linear and sensitive responses across a wide pressure range.

Proceedings of the IEEE, 1995
Through mutual technology transfer between consumer and professional video recorders, the last 20 years has witnessed a rapid evolution from analog to digital recording. Each new digital videotape recorder (VTR) uses different channel coding. This implies that improving the recording density involves the development of new channel-coding schemes ...

Video recording in ophthalmic surgery
Survey of Ophthalmology, 2019Video recording in ophthalmic surgery has immense potential to drive quality improvement in patient care, ophthalmology training, and research. Not only do surgical videos permit introspective and critical analyses of surgical technique, they also allow for objective assessment, allow for more informative audits, and are an invaluable medium for ...

Video recordings and video polysomnography
2011Publisher Summary Video polysomnography (VPSG) combines simultaneous polysomnography (PSG) and video- electroencephalography (EEG) to evaluate patients with nocturnal events. This technique has several advantages over routine PSG, including the ability to analyze behavior, correlate behavior with neurophysiologic parameters, and detect epileptiform ...

Electroencephalography and clinical neurophysiology. Supplement, 1985
Two video techniques are commonly used for biomedical monitoring. The simplest technique uses 2 or 3 video cameras with a special-effects generator. The more advanced method uses one video camera with a reformatter, a special-effects generator and a time-code generator.

Video Recording Paper - Innovation In Video Recording
SPIE Proceedings, 1984Traditionally, multiple format recording emulsions for medical video imaging have utilized a film (transparent) base. The major reason for this is probably because the film and camera manufacturers felt the diagnostician is accustomed to viewing x-ray images on a film base and would prefer to view video images that way also. Because of the need to keep
