IET calls for new “mobile data-centric” 999 service

The Institution of Engineering and Technology (IET) is calling for an “urgent” reform of the 999 emergency call service in the UK.

The change is needed, said the IET, because of users increasingly moving away from landline phones to smartphones and to devices they enable like wearables, and from voice to data.

The IET is also calling on the government to ensure that reform of the service is not allowed to drift.

Professor Will Stewart from the IET said:

“Smartphones have become the hub of our daily lives and are now in the pockets of two thirds of UK adults, and the vast majority of young people own one. Even half of 55- to 64-year-olds now own a smartphone.

“The data from Ofcom highlights the urgent need for radical changes to be made to the 999 emergency service so that those in need can text as well as call.”

According to Stewart, a data-based emergency service would allow people to text alerts via any appropriate app on a chosen easy-to-remember special number, such as 999 – and these alerts would then be passed to the human emergency operator.

The main engineering challenge would be to set up priority routing of alerts to this special number in order to avoid delays at busy times.

“Much of the technology we need to update our emergency service is available today. But we urgently need to make progress now,” said Stewart.

Microsemi makes tiny implantable radio

Microsemi has made a radio for implantable medical devices such as pacemakers, cardiac defibrillators and neurostimulators measuring 5.5×4.5×1.5mm.

RF technology is increasingly being used in a wide variety of medical implantable applications including cardiac care, physiological monitoring, pain management and obesity treatments.

The ZL70323 implantable module implements all RF-related functions needed to deploy the implant node in a medical implantable communications service (MICS) RF telemetry system, says Microsemi.

The integrated antenna tuning circuit allows the module to be used with a wide range of implantable antennas (nominal antenna impedance is 100+j150 ohms). The module provides the following major blocks:

  • ZL70103-based MICS-band RF transceiver with integrated matching network, surface acoustic wave (SAW) filter for suppression of unwanted blockers, and antenna tuning
  • 2.45 gigahertz (GHz) wake-up receiver matching network
  • Integrated 24 megahertz (MHz) reference frequency crystal
  • Decoupling capacitors and series termination resistors.

The device operates in the 402MHz–405MHz MICS band.

Multiple low power wake-up options are supported including using an ULP 2.45GHz industrial, scientific and medical (ISM) band wake-up receive option.

The ZL70103 consumes less than 6mA when transmitting or receiving and consmes only 290nA when in a periodic sleep/sniff mode (one-second sniff interval).

Murata launches MEMS acceleration sensor

MEMS angular acceleration sensor

MEMS angular acceleration sensor

Murata has launched a surface mount MEMS angular acceleration sensor, combining its technology for designing inertial sensors, such as acceleration and gyro sensors with its MEMS process technology.

Murata claims it is the world’s smallest SMD-type angular acceleration sensor measuring 5.2×2.5mm typ. x 0.8mm max.

It incorporates a detection frequency band of more than 1kHz and an angular acceleration equivalent noise effective value of less than 1rad/s²ms.

The device can be used for the detection of angular acceleration and the detection of rotational vibration.

The unit has been patent registered in Japan and overseas and has more than than 10 patents pending.

ALPS launches force sensor

ALPS launches force sensor

ALPS launches force sensor

ALPS has developed the “HSFPAR Series” force sensor, for sensing force in input devices and posture control in industrial equipment and robots, using MEMS technology to achieve the industry’s smallest size. Mass production is already under way.

Demand for high-precision pen-shaped input devices (stylus pens) has been growing with the rising popularity of digital drawing and painting. Stylus pens contain force sensors that are used to trace the trajectory of the pen tip, as well as to reproduce different thicknesses in artwork corresponding to the pressure applied. To enable smoother tone transitions, however, styli require sensors with high resolution, leading to pen shafts that are too thick, says ALPS.

The internet of things (IoT) and robotics markets have also driven up demand for compact, sensitive force sensors for applications like load detection on touch or contact, and load balance and grip strength control is expected to rise.

Force sensors today are generally either semiconductor or metallic strain gauge types, and both have their issues, the first being too big and the other sacrificing sensitivity for scale.

The HSFPAR series measure 2.00×1.60×0.66mm and can detect stress as low as 0.01N, enabling sensing of, for example, minor variations in pen pressure and load shift in robots.

It is also available as a unit type with a FPC (flexible printed circuit) included for easy integration into end products.
