Vagus Nerve

The vagus nerve [vey-guhs] is the tenth of twelve cranial nerves. Besides output to the various organs in the body, the vagus nerve conveys sensory information about the state of the body’s organs to the central nervous system. 80-90% of the nerve fibers in the vagus nerve are afferent (sensory) nerves communicating the state of the viscera to the brain. The medieval Latin word ‘vagus’ means literally ‘Wandering’ (the words vagrant, vagabond, and vague come from the same root). Sometimes the branches are spoken of in the plural and are thus called vagi.

Dive Reflex

dive reflex

The mammalian diving reflex optimizes respiration to allow mammals to stay underwater for a long time. It is exhibited strongly in aquatic mammals (seals, otters, dolphins, etc.), but exists in a weaker version in other mammals, including humans. Diving birds, such as penguins, have a similar reflex. Every animal’s diving reflex is triggered specifically by cold water contacting the face – water that is warmer than 21 °C (70 °F) does not cause the reflex, and neither does submersion of body parts other than the face.

Also, the reflex is always exhibited more dramatically, and thus can grant longer survival, in young individuals. Beyond the effect of the reflex when submerged in water, the reflex is used consciously in ‘splashing cold water on one’s face,’ either to relax when upset or wake up when drowsy. Additionally, the reflex is also elicited through water boarding torture, in order to create the sense of drowning upon the individual.

A la Carte TV

grandmas selections

A la carte cable television (from the French ‘from the menu’) refers to a model for cable companies to allow subscribers to select to which channels they would like to have access. This is in opposition to the large package deals currently prevalent in American cable deals, which often result in consumers paying for additional channels irrelevant to their interests. Leading companies such as Disney, and cable providers such as Time Warner prohibit operators from selling channels which stand alone.

Pas de Deux

pas de deux

In ballet, a pas de deux [pahduh due] (French, steps of two) is a duet in which ballet dancers perform the dance together. It usually consists of an entrée (introduction), adagio (a slow portion), two variations (one for each dancer), and a coda (literally ‘tail’). The coda is a passage which brings a movement or a separate piece to a conclusion. In ballet, the coda is usually the ‘Finale,’ a set of dances known as the Grand Pas or Grand Pas d’action and brings almost all the dancers onto the stage. A particularly large or complex coda may be called a coda Grande.

Chemex Coffeemaker, a famous coffee-making device, was introduced by the Chemex Corporation of Pittsfield, Mass. in the 1940s. It consists of a single hourglass-shaped vessel and is used to make coffee. It was invented by industrial chemist, Peter Schlumbohm; the New York Times in its obituary of Schlumbohm called the device ‘one of 100 best modern devices.’

AeroPress

aeropress championship

The AeroPress is a device for brewing coffee. It was invented in 2005 by Alan Adler. Coffee is steeped for about 10 seconds and then forced through a paper microfilter. The maker describes the result as an espresso strength concentration of coffee. The device consists of two copolyester cylinders. One cylinder has a rubber plunger and fits inside the larger cylinder to create an airtight seal, similar to a syringe.

The AeroPress, though sharing some similarities with a French press, is quite different. It uses a disposable paper filter which removes most of the coffee solids, resulting in a sediment-free brew, and air pressure is used to extract more coffee oils.

Mooncake

mooncake

Mooncake is a Chinese bakery product traditionally eaten during the Mid-Autumn Festival (Zhongqiu Festival). The festival is for lunar worship and moon watching; mooncakes are regarded as an indispensable delicacy on this occasion. Mooncakes are offered between friends or on family gatherings while celebrating the festival. The Mid-Autumn Festival is one of the four most important Chinese festivals. Today, it is customary for businessmen and families to present them to their clients or relatives as presents, helping to fuel a demand for high-end mooncake styles.

Typical mooncakes are round or rectangular pastries, measuring about 10 cm in diameter and 4-5 cm thick. A thick filling usually made from lotus seed paste is surrounded by a relatively thin (2-3 mm) crust and may contain yolks from salted duck eggs. Mooncakes are usually eaten in small wedges accompanied by Chinese tea. Mooncake calorie intake can vary with the filling and size. The average moon cake is within the calorie range of 800 to 1200.

Omni Wheel

rovio

Omni wheels (or poly wheels) are wheels with small discs around the circumference which are perpendicular to the rolling direction. The effect is that the wheel will roll with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems (those with ability to move in all direction and rotate independently). Although omniwheels are capable of movement in many directions, they are not true omni-directional wheels, a classification reserved for spherical wheels such as ball transfer units.

A platform employing three omni wheels in a triangular configuration is generally called Kiwi Drive. The Killough platform is similar; so named after Stephen Killough’s work with omnidirectional platforms at Oak Ridge National Laboratory. They are often used in small robots. In leagues such as Robocup, many robots use these wheels to have the ability to move in all directions. Omniwheels combined with conventional wheels provide interesting performance properties, such as on a six wheel vehicle employing two conventional wheels on a center axle and four omniwheels on front and rear axles.

Mecanum Wheel

mecanum wheel

The Mecanum wheel is one design for a wheel which can move in any direction. It is sometimes called the Ilon wheel after its Swedish inventor, Bengt Ilon, who came up with the idea in 1973 when he was an engineer with the Swedish company Mecanum AB. It is a conventional wheel with a series of rollers attached to its circumference. As well as moving forward and backward like conventional wheels, they allow sideways movement by spinning wheels on the front and rear axles in opposite directions.
