Effective communication is crucial for any engineering project. In many cases, traditional communication methods fall short, especially in remote locations or areas with limited network coverage. This is where two-way radio communication comes into play. Two-way radios, commonly known as walkie-talkies, provide reliable, real-time communication, making them an indispensable tool for engineers. In this comprehensive
Walkie talkies are widely used across the public, commercial and private sector. Digital walkie talkie is a handheld portable two way radio with a push to talk button to start transmission. It is a single unit that resembles with a telephone headset. Digital walkie talkie allows only one channel of communication which means only one
When choosing the right walkie talkie earpiece, it is important to consider various factors that would ensure a satisfying user experience. Let's explore!
Most cable connection providers commonly offer coaxial cable internet. The coaxial internet sends a data signal through the coaxial cable to the modem to a domestic user’s location. The data is transmitted through the modem's Ethernet connection to a computer, delivering high-speed internet access. Performance of cable The internet data travels inform of packets, that
Digital two-way radios are used globally to help individuals and businesspersons in quick communications. Two-way radio provides the ideal solution for communication. Walkie-talkies can be attached with telephone systems, alarm panels with WI-FI in universities and multiple departments that enhance the way of communication. Two-way radios are based on transmitting radio signals and cover large
Copyright © Françoise Herrmann For humans, an exoskeleton (with the Greek prefix exo-, meaning “outer”, in contrast to the prefix endo- meaning “inner”) is a robotic brace, suit or vest, designed to support a person’s own endoskeleton, or parts thereof. Exoskeleton applications exist both in medicine and industry. The research is also funded by the US Arny. In industry, for example at the Ford Motor Company assembly line, robotic exoskeleton vests called Eksovests are used to assist workers who have to perform repetitive overhead movement with their arms. In the construction industry, metal exosuits, such as for example the Ekso Works Industrial Exoskeleton, are used to give workers robotic upper body strength for lifting and carrying heavy loads, or for operating power tools. In medicine, robotic exoskeletons bring much hope and/or an upright view of the world to victims of stroke, disease or accidents, in particular to patients, who for one reason or another cannot walk or experience great difficulty walking. For example, in pediatric medicine, robotic exoskeleton braces exist for children with cerebral palsy. The robotic braces provide motorized knee extension in view of alleviating the children’s crouch (or flexed- knee) gait, which otherwise risks preventing them from walking in adulthood. Post-stroke victims also benefit from robotic exoskeleton training for gait rehabilitation, using such exoskeletons as the H2. For a very high price ($40,000), exoskeleton suits, such as SuitsX, a spinoff developed at UC Robotics and Human Engineering Laboratory, also enable paraplegic patients to walk, offering an opportunity to stand up and see others eye to eye, to stretch and extend limbs in view of avoiding sores and other wheelchair side effects. Finally, in geriatric medicine, exoskeletons such as Superflex, an SRI International spinoff, are designed to enhance elderly mobility, and to effectively compete with walkers. As one of several companies developing exoskeletons, Ekso Bionics has an extensive portfolio of patented technologies. In particular, the US patent application, US20130231595A1, titled Human Machine interface for human exoskeleton recites a robotics invention addressing mobility. A robotics invention that notably addresses how the exoskeleton can be driven by sensors which read and anticipate the user's movements, in contrast to exoskeletons which are activated manually with onboard buttons, or joysticks. For Ekso Bionics, robotic sensing of the user's movement (in turn actuating the robotic exoskeleton) vs manual control, is really what enhances the experience of walking. The abstract of this patent application is included below, together with figure 1 of the patent drawings, showing a user coupled to an exoskeleton equipped with robotic walking asistance. A powered exoskeleton configured to be coupled to lower limbs of a person is controlled to impart a movement desired by the person. The intent of the person is determined by a controller based on monitoring at least one of positional changes in an arm portion of the person, positional changes in ahead of the person, an orientation of a walking aid employed by the person, a contact force between a walking aid employed by the person and a Support Surface, a force imparted by the person on the walking aid, a force imparted by the person on the walking aid, a relative orientation of the exoskeleton, moveable components of the exoskeleton and the person, and relative velocities between the exoskeleton, moveable components of the exoskeleton and the person.

Coaxial cables are used in homes and offices for various audio and video appliances. These cables are popularly used in telecommunication, cable TV, CCTV, and internet connections. Despite the availability of more advanced technology, the demand for coaxial cable is still huge and many consumers prefer them over optic fibre and ethernet due to low cost and better durability. With the diverse application of coaxial cables, they are designed to fit the different needs of users. This is the reason a variety of coaxial cable is available in the market. Not all cables are the same and each coaxial is made to meet a certain standard of specification. They greatly vary in design which ultimately affects their performance and suitability for a particular application. Irrespective of the fact, if you need these cable for your domestic needs or for commercial installation, it is important that you understand the basic features of the cables and buy accordingly. Selecting the right cable to meet your needs can have a serious impact on your satisfaction towards your purchase. Type of cables Depending upon the type of signals they transmit coaxial cables can be divided into RF cables, Microwave cables and digital cables. RF cables are mostly used for TV sets and internet connections whereas microwave cables are installed in communication systems, satellite connections and military gadgets. Digital coaxial cables are frequently used to connect sound systems with subwoofers and their quality is comparable to the optical fibre. Transmission Impedance Impedance refers to the strength of the signal the cables are capable of transmitting. Impedance Depends upon the central layer of cable, particularly the capacitance of the cable over a meter in relation to its inductance over a meter. On the basis of these characteristics, coax cable is divided into two categories, 750 Ω and 500 Ω impedance cables. The first type is used for video application while the other is used mostly for data and wireless connections. Cable attenuation and Operating Frequency For higher signal frequency the signal energy starts moving away from the centre of the cable towards the outer layers. This is referred to as “skin effect” which leads to signal loss, and due to this effect, higher frequencies can only travel to shorter distances. Thicker cables will be able to handle higher frequency translation without much loss in the strength of the signal. The signal loss for the longer distance should be one of the factors to consider if you are planning for commercial applications.
