Touch probe. Touch probes are tools used for precision measurements in CNC (Computer Numerical Control) machining processes. They work in a way similar to Coordinate-measuring devices. Probes are used to adjust different offsets when setting up a machining job. They can help make adjustments to tool lengths, diameter and length offsets as well as  measuring various other workpiece dimensions. Probing systems can significantly reduce the time required for tool changes and adjustments in work-holding setups, and can streamline manufacturing processes.

Usage and Types
The capability for accurate and automatic measurements provided by touch probes is an important part of setting up unmanned operations in modern manufacturing environments.
Touch probes differ from a standalone coordinate-measuring machine in that they are typically used on the machine cutting materials. While commonly used in milling machines with automatic tool change systems, touch probes can also be manually swapped with cutting tools and are often paired with a CNC Milling Tool Height Setter for optimized performance.

Types

   Touch Probes - A sensor used to measure coordinates on a machine.
   Tool Length Sensor - A sensor used to set tool length offsets after a tool change.

Operation

In CNC machining, when something has been partially machined and needs more operations performed in a different position, it can be difficult to position the machine and restart operations in a needed location of the modified coordinates. For example, something needs to be flipped over to be machined on the opposite side. In this case, a probe can be put into the tool holder and programmed with G-code or other methods to touch off the work-piece, telling the machine where everything now is. After the machine knows everything's location, offsets are adjusted to start the next operation after the probe has been removed from the tool holder.  

The technology reduces manual measurement errors and also improves machining accuracy, speeds up the setup process, and enables more sophisticated and precise manufacturing capabilities.

History

The development of precision probes dates back to the 1920s with different mechanical touch devices, but significant advancements came with the advent of Coordinate Measuring Machines (CMM) in the late 1950s. This led to the creation of contact and non-contact probes, including mechanical triggers and scanning probes, as well as laser and optical video probes. Mechanical probes, the earliest form of precision measurement tools, rely on direct contact for measuring and are now rarely used due to their lower precision. Trigger probes, popularized by Renishaw in the 1970s, utilize pulse signals to determine contact point coordinates, offering precise measurements.

Satellite data unit. A satellite data unit (SDU) is an avionics device installed in an aircraft that allows air/ground communication via a satellite network. It is an integral part of an aircraft's SATCOM (satellite communication) system. The device connects with a satellite via ordinary radio frequency (RF) communication and the satellite then connects to a ground station or vice versa. All satellite communication whether audio or data is processed by the SDU.

The SDU communicates with an onboard MDDU (multi-purpose disk-drive unit) which maintains an updatable table of ground stations near the aircraft's position and the order of preference for selection of which ground station to use which thus guides the choice of satellite. Along with analysing data continuously sent from all ground stations (such as station status and the error rate of signals from each station) the SDU receives information on the aircraft's position and orientation from another onboard system (ADIRU, air data inertial reference unit) which it passes to the BSU (beam-steering unit) to direct the signal beam from the aircraft to the chosen satellite.

With the advent of cellphones and the Internet a separate or integrated SDU can be used to offer telephone and Internet services to passengers.

Logs of satellite communication have been used to inform search and rescue agencies of locations of missing aircraft, like Malaysia Airlines Flight 370 whose position was unknown due to loss of radar contact and other communications. Automated SATCOM transmissions suggested it flew about  off its designated flight path having flown approximately south-southwest rather than the intended approximately north-northeast.

MMPL Kanpur. The MMPL Kanpur was an Indian light four-seat aircraft, designed for service and agricultural work in the early 1960s. It is a rare example of an aircraft designed and built by a national air force for its own use.

Design and development
The Kanpur I was designed by an Indian Air Vice-Marshal and built in 132 days at the Indian Air Force Maintenance Command Development Centre at their Kanpur air base. A more powerful version, the Kanpur II, was intended for production as a military general-purpose and army observation machine, though serious consideration was also given to an agricultural role.  For this, the prototype Kanpur I was fitted with spray bars. The Kanpur I dates from about 1960 and the Kanpur II first flew in October 1961.

The four-seat Kanpur was a conventional single-engine, braced high-wing monoplane with a fixed conventional undercarriage. It had a steel structure, mostly fabric-covered. The constant chord wings were built around two spars and with 1° 26' of dihedral. They were braced on each side with a pair of V-struts from the two spars to the lower fuselage longerons. Metal-skinned split flaps and fixed leading edge slots were fitted.

The fully glazed cabin was under the wing, with the four occupants in two rows of side-by-side seats. The Kanpur pilot had standard blind flying instrumentation and a STR-9X radio. The air-cooled engine, a flat four in the Kanpur I and a flat six in the Kanpur II, drove a two-blade propeller. The Kanpur's main wheels were mounted on cantilever, faired legs attached to the lower fuselage through liquid shock absorbers. There was a small tailwheel at the extreme tail, where the tailplane was placed on the upper fuselage.  The elevator had a cut-out for the rounded rudder which extended to the keel, hung on a fin smoothly merged into the upper fuselage.

Variants
Kanpur I: Prototype, with a four-cylinder,  Lycoming air-cooled horizontally opposed engine.

Kanpur II: Intended for production with a six-cylinder,  Lycoming air-cooled horizontally opposed engine. It was  longer, a little heavier on take-off and had a maximum speed  greater.

Didicar. Didicar is a self-propelled ride on toy made of polypropylene designed for children aged 3 years and up. The Didicar starts moving when the rider turns the steering wheel left and right. Thanks to the rotation of the steering wheel, the Didicar leverages its frictional force, gravity and inertia to move forward and backward. It is designed for hard, smooth or flat surfaces, both indoors and outdoors. It has no pedals, motors, batteries or greasy chains.

Design 
The Didicar looks like a four-wheeled scooter with a steering wheel in front. The child drives the Didicar seated on the seat with their feet resting on the front foot plates and with the legs surrounding the steering column. The Didicar has 6 wheels, 2 at the back and 4 in the front. Only the 2 rear wheels and two front Drive Wheels touch the floor. The first two wheels at the front of the front wheel assembly never touch the floor and help maintain stability and security in case the child leans forward. The larger front drive wheels of the front wheel assembly are connected to the steering wheel through a steering column. These are the wheels that move the vehicle. The rear wheels have independent rotation. The body and wheels are made of polypropylene, while roller bearings and other metal parts are made from stainless steel.

Didicar is designed for children from 3 years and adults with a maximum weight of up to 120 kg, and can reach speeds up to 6 mph. It's designed for use on hard, smooth, flat surfaces, both in indoors and outdoors. It's available in several different colours including blue, green, purple, pink, red and yellow.

History and marketing 
Didicar was introduced to the UK and Ireland in 2004 by Simac Marketing Ltd and is distributed in Spain and Portugal by Toycy Toys. It is sold for use as a domestic toy, as well as in schools.

Salomón Cohen Levy. Salomón Cohen Levy (28 May 1927 – 24 June 2018) was a Moroccan Jewish-Venezuelan civil engineer and real estate businessman. He was the founder and owner of the construction company Sambil.

Biography

Salomón Cohen was born in Jerusalem, then in the British Mandate of Palestine, into a Moroccan Jewish family which resided in the Spanish protectorate in Morocco. His family moved to Caracas, the capital of Venezuela, at the age of three, when his father Ezra Sión Cohen looking for a better future in the thriving Latin American country. He studied at the Liceo Andrés Bello.

In 1951, he obtained a degree in civil engineering at the Central University of Venezuela. He started his career as an engineer at the Ministry of Public Works and Housing during the mandate of President Marcos Pérez Jiménez in 1953. He left his post at the ministry and was appointed as manager at Banco Obrero. Cohen was a member of the Israelite Association of Venezuela.

Business ventures and investments

In 1953 he founded Constructora Sambil, and became a real estate businessman. His first major project was the Lido shopping mall located in El Rosal, Caracas; with a mix of offices and hotel rooms, it gave birth to the Lidotel chain. In 1998 it expanded into a growing developing business, the building and administration of shopping malls, opening the Centro Sambil located in Chacao. Later on more Shopping malls openings followed in other cities in  Venezuela, Curaçao and the Dominican Republic.

In 2012, his company purchased the Spanish shopping mall Avenida M-40, which closed in 2010 due to the effects of the economic crisis of 2008. Sambil was renovating it and planned to re-open it as an outlet center in the summer of 2015. It will be renamed Sambil Outlet Madrid.

After his death on June 24, 2018, all Sambil shopping malls in the country closed their doors for three days as a sign of mourning.
